Question

The table below shows the number of scooters asold at a store during three-year period

Answer 1

2, 240

Explanation:

In the table, the values should be

Year 1 725

Year 2 579

Year 3 696

Since Year 4 sold 112% of the previous 3 years combined, we add 725+579+696=2000. We can find 112% by writing a proportion.

`(112)/(100) =(x)/(2000)`

We solve through cross multiplication of numerator and denominator of the opposite fraction.

`112(2000)=100(x)\\224000=100x\\2,240=x`
