1. An item price at P3,600 has a 25% discount. Find the
discounted price.
2. John lives twice as far from school as Mona does. If
the total distance that John and Mona travel every
school day is 8.7 km, how far from school does John
live?
3. Find two consecutive integers whose sum is 143.
(hint: let x-the first integer, X+1-second integer)
Answer:
1. 3600 x 25 ÷100 =900
there fore the discount price is p900
3. it means if you add to integers you get 143
so x +x+1=143
2x +1=143
2x+1-1=143_1
2x=142
2x/2 =142/2
x=71
x+1=71+1=72

a cinema has three screens last saturday there were 500 visitors
Answer:
200 visitors went to screen 1.
125 visitors went to screen 2.
175 visitors went to screen 3.
Step-by-step explanation:
We will find number of visitors who went to screen 1 by finding 40% of 500 as we are told that 40% of 500 visitors went to screen 1.
Therefore, 200 visitors went to screen 1.
Now we will find number of visitors who went to screen 2. We are told that 25% of 500 visitors went to screen 2.
Therefore, 125 visitors went to screen 2.
Now we will find the number of visitors who went to screen 3 by subtracting combined number of visitors who went to screen 1 and screen 2 from total number of visitors.
Therefore, 175 visitors went to screen 3.

Brianna is going to invest in an account paying an interest rate of 5.2% compounded daily. How much would Brianna need to invest, to the nearest ten dollars, for the value of the account to reach $6,600 in 11 years?
Answer:
3398.1761
Step-by-step explanation:
Using compound interest relation:
A = P(1 + r/n)^nt
5.2 / 100 = 0.052
n = 365 * 12 = 4380
6000 = P(1 + 0.052/4380)^4380*11
6000 = P(1.0000118)^48180
6000 = 1.7656530P
P = 6000/ 1.7656530
P = 3398.1761

Factor out the gcf
-240c^2+ 30c^5+ 18c^4
Answer:
6c^2(-40 + 5c^3 + 3c^2)
Step-by-step explanation:
These three terms have the common factor c^2. Thus:
-240c^2+ 30c^5+ 18c^4 = c^2(-240+ 30c^3+ 18c^2).
Recognizing that 6 is common to all three terms inside the parentheses, we get:
6c^2(-40 + 5c^3 + 3c^2) This is as far as factoring of this expression can be taken.

It is often used to represent ratios and proportions in a more convenient and understandable form, especially in financial and statistical contexts. For example, 50% means 50 per 100, or half of a given quantity. It is denoted using the symbol "%".
Given that,
After a few mathletes join the team, the team is able to solve 40% more problems per session
Let X be the number of problems the team was able to solve before the new mathletes joined.
We know that after the new mathletes joined, they were able to solve 42 problems per session, which is 40% more than before, so:
X x 1.40 = 42
Solving for X:
X = 42 / 1.40 = 30.
