Answer 1

10. 9/40

11. $72

Explanation:

10.

Step 1: Have the whole cake as 1,

`1-(1)/(8) -(2)/(5) -(1)/(4)\\= 1 -(5)/(40)-(16)/(40)-(10)/(40) \\= (9)/(40)`

11.

Step 1: Find the remaning income left

`1-(5)/(16)-(1)/(4)-(1)/(24) -(1)/(48) \\= (3)/(8) \\`

Step 2: Calculate the weekly income

3 units = $27

1 unit = $9

Weekly income = $9 * 8 = $72
