12. [tex]10.01 p + 9.96 \leq 50[/tex] so [tex]p \leq 4[/tex]

Step-by-step explanation:

1. Given

[tex]Expression: 15a + 6[/tex]

Required

Determine the equivalent expression

[tex]Expression: 15a + 6[/tex]

Expand:

[tex]Expression: 3 * 5a + 3 * 2[/tex]

Factorize:

[tex]Expression: 3(5a + 2)[/tex]

Hence, the equivalent expression of the given expression is [tex]3(5a + 2)[/tex]

2.

Given

[tex]Charges = \$6.25[/tex]

s = seventh grade students

g = eight grade students

Required

Determine the total charges

First, we need to calculate the total number of charges:

[tex]Total=s+g[/tex]

[tex]Total\ charges = Charges * Total[/tex]

[tex]Total\ charges = 6.25(s+g)[/tex]

3. Given

Ken

[tex]Duration = x\ weeks[/tex]

[tex]Extra\ Earnings = \$18[/tex]

[tex]Weekly\ Earnings = \$65[/tex]

Paul

[tex]Weekly\ Earnings = \$65[/tex]

[tex]Duration = y\ weeks[/tex]

Ken's total charges is:

[tex]Weekly\ Earnings * Duration + Extra\ Earnings[/tex]

[tex]65 * x + 18[/tex]

[tex]65x + 18[/tex]

Paul's total charges is:

[tex]Weekly\ Earnings * Duration[/tex]

[tex]65 * y[/tex]

[tex]65 y[/tex]

[tex]Total = Ken + Paul[/tex]

[tex]Total = 65x + 18 + 65y[/tex]

4.

To calculate the percentage, we simply divided the number of pop albums by the total number of albums.

For Michelle.

[tex]\%Pop = \frac{33}{60} * 100\%[/tex]

[tex]\%Pop = \frac{3300\%}{60}[/tex]

[tex]\%Pop = 55\%[/tex]

For Sasha

[tex]\%Pop = \frac{36}{78} * 100\%[/tex]

[tex]\%Pop = \frac{3600\%}{78}[/tex]

[tex]\%Pop = 46.2\%[/tex]

For Kat:

[tex]\%Pop = \frac{40}{89} * 100\%[/tex]

[tex]\%Pop = \frac{4000\%}{89}[/tex]

[tex]\%Pop = 44.9\%[/tex]

For Monica:

[tex]\%Pop = \frac{24}{59} * 100\%[/tex]

[tex]\%Pop = \frac{2400\%}{59}[/tex]

[tex]\%Pop = 40.7\%[/tex]

From the calculation above, Michelle has the highest percentage of Pop music

5.

[tex]People = 80[/tex]

[tex]Fortnite = 0.55[/tex]

[tex]Among\ Us = 30\%[/tex]

Required

Determine number of friends that prefer fortnite more than among us

First, we need to calculate the number of people that prefer Fortnite.

[tex]Fortnite = 0.55 * 80[/tex]

[tex]Fortnite = 44[/tex]

Next, we need to calculate the number of people that prefer Among Us.

[tex]Among\ Us = 30\% * 80[/tex]

[tex]Among\ Us = 24[/tex]

The difference is:

[tex]Difference = 44 - 24[/tex]

[tex]Difference = 20[/tex]

Hence, 20 more people preferred Fortnite to Among Us

6.

[tex]Hulk = 0.25[/tex]

[tex]Iron\ Man = 12[/tex]

[tex]Thor = 35\%[/tex]

Captain America cleaned the rest

[tex]Total = 60[/tex]

Number of cities by each is:

[tex]Hulk = 0.25 * 60[/tex]

[tex]Hulk = 15[/tex]

[tex]Iron\ Man = 12[/tex]

[tex]Thor = 35\%[/tex]

[tex]Thor = 35\% * 60[/tex]

[tex]Thor = 21[/tex]

[tex]Captain\ America = 60 - 15 -12 - 21[/tex]

[tex]Captain\ America = 12[/tex]

By comparison, Thor cleaned the highest number of cities

7. This question is not clear

[tex]Total = \$70[/tex]

[tex]Glass = \$30[/tex]

[tex]Each\ Cape = \$8[/tex]

Let the number of cape be x.

We have that:

[tex]8 * x + 30 \leq 70[/tex]

[tex]8 x +\leq 70 - 30[/tex]

[tex]8 x +\leq 40[/tex]

[tex]x\leq 5[/tex]

9.

Let the first number be x and the second be y

[tex]x + y = 32[/tex]

[tex]y = x + 5[/tex]

Substitute x + 5 for y in the first equation

[tex]x + x + 5 = 32[/tex]

10.

[tex]Savings = \$9[/tex]

Earnings = $7 per hous

Total = $44

The inequality is:

[tex]7 * n + 9 \leq 44[/tex]

[tex]7n + 9 \leq 44[/tex]

[tex]7n \leq 44 - 9[/tex]

[tex]7n \leq 35[/tex]

[tex]n \leq 5[/tex]

11.

Earnings = $40

Extra = $5 per lasso

Total Earnings = At least $70 daily

The inequality is:

[tex]40 + 5n \leq 70[/tex]

[tex]5n \leq 70 - 40[/tex]

[tex]5n \leq 30[/tex]

[tex]n \leq 6[/tex]
