Answer 1

savings = $360

spending = $160.

Explanation:

saving : spending

9 : 4

total amount = $520

add the two parts in the ratio(9+4) to get the total parts.

9 + 4 = 13parts . so, 13 parts = 520.

what about 9 and 4?

13 = 520

9 = ?

9 × 520/13 = 360

4 × 520/13 = 160.

hope this helps.

Answer 2

Savings = $ 360

Spending = $ 160

Explanation:

Savings: spending = 9 : 4

Total part = 9 + 4 = 13

Part of saving = 9/13

Savings = (9/13) of 520

`=(9)/(13)*520\\\\=9*40`

= $ 360

Spending = 520 - 360 = $ 160
