Printer A prints 36 pages every 1.5 minutes. Printer B prints 114 pages every 3 minutes. Printer C prints 115 pages every 5 minutes Which printer prints the fastest?

Printer B

Step-by-step explanation:

If printer A prints 36 pages every 1.5 minutes (90 seconds) we can divide 90 seconds by 36 to determine how long it takes Printer A to print one page. When we do that, we get 2.5 seconds which means it takes Printer A 2.5 seconds to print one page.

If we do the same with Printer B, we can divide 3 minutes (180 seconds) by 114 to get about 1.5 seconds which means it takes Printer B about 1.5 seconds to print one page.

If we do the same with Printer C, we can divide 5 minutes (300 seconds) by 115 to get about 2.6 seconds which means it takes Printer C about 2.6 seconds to print one page.

From this we can determine which printer prints the fastest and our answer will be Printer B.

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
