Richard had twice as much money as Precious at first. After Precious spent $23.10, Richard had 8 times as much money as Precious. How much did Richard have? And the answer is not 61.60

Answer 1

Let's assume Precious had x amount of money at first.

Since Richard had twice as much money as Precious at first, he had 2x amount of money.

After Precious spent $23.10, she had (x - 23.10) amount of money.

According to the given condition, Richard had 8 times as much money as Precious after she spent $23.10. So, we have the equation:

2x - 23.10 = 8(x - 23.10)

Expanding the equation, we get:

2x - 23.10 = 8x - 184.80

Subtracting 2x from both sides:

-23.10 = 6x - 184.80

Adding 184.80 to both sides:

161.70 = 6x

Dividing both sides by 6:

x = 26.95

Therefore, Richard had 2x = 2 * 26.95 = $53.90 at first.
