Question

Sam puts 1/5 of his newspaper selling money in savings and uses 1/8 of the remaining money to buy a movie. If he has $14 left. How much did he have at first?

Answer 1

Answer:

$20.

Step-by-step explanation:

Let x be the amount of money he had originally, then:

x - 1/5 x - 1/8(x - 1/5 x)  = 14

x - 1/5x - 1/8x + 1/40x = 14

0.7 x = 14

x = 140/7

x = 20.

Answer 2

Answer:

Correct answer: x = 20$

Step-by-step explanation:

The required equation for this situation is:

1/5(x) + 1/8(4/5(x)) + 14 = x  => 1/5 (x) + 4/40(x) + 14 = x =>

1/5(x) + 1/10 (x) + 14 = x

we will multiply both sides of the equation by 10 and get

2 x + x + 140 = 10 x => 10 x - 3 x = 140 => 7 x = 140 => x = 140/ 7

x = 20$
