Ace manufacturing ordered 17 boxes with 85 ball bearings each. they also ordered 15 boxes with 90 spring each. how many more ball bearings than springs did they order?

Answer

95

Explanation

One box has 85 ball bearings.

17 boxes = 17 × 85

               = 1,445 ball bearing

One contains 90 springs

15 boxes ⇒ 15 × 90

               ⇒ 1,350 spring

Number of ball bearing more than springs are;

1445 - 1350 = 95
