Question

At the beginning of the school year, the batteries and all the graphing calculators were replaced. Each calculator required 4 batteries. Office Plus offered a back to school special price of $32.98, including tax, for a package of 20 calculator batteries. How much did it cost to replace the batteries in 110 graphing calculators?

Option 1: $131.92
Option 2: $181.39
Option 3: $659.60
Option 4: $725.56

Answer 1

The cost to replace the batteries in 110 graphing calculators is $725.56.

Step-by-step explanation:

To find the cost of replacing the batteries in 110 graphing calculators, we need to determine the cost per calculator and then multiply it by the number of calculators.

Given that a package of 20 calculator batteries costs $32.98, including tax, we can calculate the cost per battery by dividing the total cost by 20. So, the cost per battery is $32.98 / 20 = $1.649.

Since each calculator requires 4 batteries, the cost to replace the batteries in one calculator is $1.649 x 4 = $6.596. Finally, to find the cost of replacing the batteries in 110 calculators, we multiply the cost per calculator by the number of calculators: $6.596 x 110 = $725.56.
