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
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.
