Answer:
x - [1.95 + 30 + 7.20 + [tex]\frac{2}{3}[/tex]{x - (1.95 + 30 + 7.20)}] = 38.5
Step-by-step explanation:
Let the total amount of money Liza has = $x.
Then, According to the question we get equation,
x - [1.95 + 30 + 7.20 + [tex]\frac{2}{3}[/tex]{x - (1.95 + 30 + 7.20)}] = 38.5
⇒ x - [39.15 + [tex]\frac{2}{3}[/tex]{x - 39.15}] = 38.5
⇒ x - 39.15 - [tex]\frac{2}{3}[/tex]{x - 39.15} = 38.5
⇒ x - 39.15 = 3 × 38.5
⇒ x - 39.15 = 115.5
⇒ x = 154.65
Thus, she earned $154.65 by taking care of her neighbor's pet.
