Answer:
$2
Step-by-step explanation:
The price of each calculator is found by dividing the box price by the number of calculators in the box.
$30/5 -$32/8 = $6 - $4 = $2
In boxes of 8, each calculator costs $2 less.
Buying boxes of 8 calculators each for $32 is $2 cheaper than the buying boxes of 5 calculators each
If boxes of 8 calculators cost $32, then each box of calculator will cost
$32/8 = $4
If Boxes of 5 calculator cost $30, then each box of calculator will cost
$30/5 = $6
The difference between the two price is $6 - $4 = $2
Therefore buying boxes of 8 calculators each for $32 is $2 cheaper than the other
decrease by 20%
