Answer:

Step-by-step explanation:

(1)

To find the unit rate divide the amount by 3

$3.84 ÷ 3 = $1.28 ← unit rate

(2)

Using proportion

$45 → 4 months

$180 → 4 × $\frac{180}{45}$ = $\frac{4(180)}{45}$ = 16 months

(3)

sum the parts of the ratio, 8 + 1 = 9 parts

Divide 90 by 9 to find the value of one part

90 ÷ 9 = 10 ← value of 1 part

Thus

8 × 10 = 80
