Zach earns $37.50 every weekend for delivering newspapers. Zach is saving his earnings in order to buy a new computer that costs $470.80. If Zach already has $58.30, enter the minimum number of weekends Zach will need to work before he has enough money to buy the computer.

Answer 1

To determine the minimum number of weekends Zach needs to work to save enough for the computer, we first need to calculate how much more money he needs to save.

1. Cost of the computer: $470.80
2. Amount Zach already has: $58.30

Now, we find the remaining amount Zach needs:

\[ \text{Remaining amount} = \text{Cost of the computer} - \text{Amount Zach already has} \] \[ \text{Remaining amount} = 470.80 - 58.30 = 412.50 \]

Next, we know that Zach earns $37.50 each weekend. To find out how many weekends he needs to work to earn at least $412.50, we divide the remaining amount by his weekend earnings:

\[ \text{Number of weekends} = \frac{\text{Remaining amount}}{\text{Earnings per weekend}} = \frac{412.50}{37.50} \]

Now we calculate:

\[ \frac{412.50}{37.50} = 11 \]

Thus, Zach needs to work a minimum of 11 weekends to save enough money to buy the computer.

Therefore, the answer is 11.
