Question

A particular lawn mower is on sale at two different stores the original price at both stores was $130. Watson’s garden shop is advertising the lawn mower for 50% off. Hartman’s home center reduced the mower 40%, and then took an additional 15% off the reduced price. Which lawn mower is the better deal?

Answer 1

Watson's garden shop has the better deal on the lawn mower.

Hope this helped :)

Explanation:

Watson's $130 - 50% = $65

Hartman's $130 - 40% = $78

$78 - 15% = About $66

Answer 2

The deal of Watson’s garden shop is better.

Explanation:

Given,

The original price = $ 130,

After 50% off,

The new price would be,

`P_1=130* ((100-50))/(100)`

`=(130* 50)/(100)`

`=(6500)/(100)`

`=\$ 65`

While, after 40% off then additional 15% off,

The new price would be,

`P_2= 130* ((100-40))/(100)* ((100-15))/(100)`

`=130* (60)/(100)* (85)/(100)`

`=(663000)/(10000)`

`=\$ 66.30`

∵ 66.30 > 65

Hence, first deal is better.
