Answer 1

Answer:

2287.5

Step-by-step explanation:

In January,

2x + 3x + 4x + 5x = 4200

14x = 4200

x = 300

Shali's income = 4 × 300 = 1200

In February ,

3x + 4x + 5x + 2x = 4200 × 2

14x = 4200 × 2

x = 600

Shali's income = 5 × 600 = 3000

In March,

4x + 5x + 3x + 2x = 4200 × 3

14x = 4200 × 3

x = 900

Shali's income = 3 × 900 = 2700

In April,

4x + 3x + 5x + 2x = (4200 × 3) ÷ 2

14x = (4200 × 3) ÷ 2

x = 450

Shali's income = 5 × 450 = 2250

Hence average monthly income = (1200 + 3000 + 2700 + 2250) ÷ 4 = 2287.5
