Afactory produced 8,500 soccer balls last year, and 9,265 this year. what was the percent of increase in production? a. 8.0% b. 8.5% c. 9.0% d. 9.5%

9.0%

Explanation:

9,265/8,500=1.09

Thus, 9,265 is 109% of 8,500. This means a 9% increase from 8,500.

Check:

8,500*0.09=765

8,500+765=9,265

a) at most means it can cost $12 or less

so the inequality sign would be ≤

you would then need to multiply the number of toppings by the 0.35 for each one and add it to the cost of the cheese pizza.

the equation would be 9.99 + 0.35x ≤ 12

b) using the above equation:

9.99 + 0.35x ≤ 12

subtract 9.99 from each side:

0.35x ≤2.01

divide both sides by 0.35:

x ≤ 2.01 / 0.35

x ≤5.74

at most you could have 5 toppings.

the 5 topping pizza would cost: 0.35 x 5 = 1.75 + 9.99 = $11.74
