Jennifer has one more nickel than she has dimes. If she has $1.25 how many of each type of coin does she have? (HELP IS APPRECIATED)
Answer:
She has 9 nickels, and 8 dimes.
Step-by-step explanation:
We know that she has a total of $1.25. We know that a nickel is $0.05, and that a dime is $0.10.
9x$0.05=$0.45
8x$0.10=$0.80
Answer:
9 nickels
8 dimes
Step-by-step explanation:
.05(n + 1) + .10n = 1.25
.05n + .05 + .10n = 1.25
.15n = 1.20
n = 1.2 / .15
n = 8
but there are 9 nickels because there is "one more nickel than dimes"

Melissa earns a 2% commission on the first $750 of sales she makes each week. She earns a 3% commission on the amount of her sales that are greater than $750 each week. Melissa earned $37.50 in commissions last week.
Which equations correctly calculate how much money in dollars, x, Melissa made in sales last week?
Select all that apply.
0.02(750)+0.03(750−x)=37.5
0.03(x−750)=37.5−15
15+0.03x−22.5=37.5
0.02(750)+0.03(x−750)=37.5
15−0.03x+22.5=37.5
0.03(750−x)=37.5−15
The equations that are correct are:
0.02(750) + 0.03(x - 750) = 37.5
0.03(750 - x) = 37.5 - 15
Given:
Melissa earns a 2% commission on the first $750 of sales.
She earns a 3% commission on greater than $750 each week.
1. Sales up to $750:
Melissa earns a 2% commission on the first $750 of sales.
=0.02(750)
= 15
2. Sales exceeding $750:
Melissa earns a 3% commission on the amount of sales that exceed $750.
0.03(x - 750) = 37.5 - 15
Combining both equations, we have:
0.02(750) + 0.03(x - 750) = 15 + 37.5 - 15
15 + 0.03x - 22.5 = 37.5
0.03x - 7.5 = 37.5
Adding 7.5 to both sides
0.03x = 45
Dividing both sides by 0.03
x = 1500
Therefore, the correct equations that calculate the amount of money Melissa made in sales last week are:
Equation 1: 0.02(750) + 0.03(x - 750) = 37.5
Equation 2: 0.03(750 - x) = 37.5 - 15

Charlotte invests £5000.
The bank pays 10% interest for the first year and then y% every year after that.
After three years, Charlotte has £5610.55
Calculate y
Answer:
y = 1%
Step-by-step explanation:
From the formula;
Interest; i = PRT/100
P = £5000
R = 10%
After 1 year, we have;
i = 5000 × 10 × 1/100 = £500
Amount is now; 5000 + 500 = £5500
Since interest rate is now y% every year after the first one, then;
After 2nd year;
i = (5500 × y × 1)/100
i = 55y
So amount is now;
5500 + 55y
After 3rd year, interest is now;
i = (5500 + 55y) × y × 1/100
i = 55 + 0.55y²
Amount is now;
(5500 + 55y) + (55 + 0.55y²)
Since she has £5610.55 after 3 years, then;
(5500 + 55y) + (55 + 0.55y²) = 5610.55
0.55y² + 55y + 5555 - 5610.55 = 0
0.55y² + 55y - 55.55 = 0
From quadratic formula, y = 1%
Mr. Brady asked his students how long it took them to complete their homework from the previous night. He presented the results in the line plot shown. How many minutes did the greatest number of students take to do their homework? How many combined hours did those particular students spend on homework explain.
Answer:
The question is lacking the accompanying line plot, I found a matching line plot online:
Answers:
a) The number of minutes te greatest number of students took to do their homework = 40 minutes
b) The number of combined hours the students spent on their homework [tex]= 5\frac{1}{3}\ hours[/tex]
Step-by-step explanation:
From the diagram, the greatest number of students ( 8 students) take 2/3 hours to do their homework. Converting this time to minutes:
1 hour = 60 minutes
∴ 2/3 hours = 60 × 2/3 = 120/3 = 40 minutes
∴ 40 minutes is the time the greatest number of students take to do their homework
b) combined hours those students did their homework is calculated as follows:
total time = (number of hours used by 1 student) × number of students
[tex]Total\ time = \frac{2}{3} \times 8 = \frac{16}{3}\\= 5\frac{1}{3} \ hours[/tex]
