Benny opened a bank account. He deposited $92.50 into his account every month for 10 months. He used $36.50 every month to pay for art lessons. After 10 months, he used 1 over 2 of the total money left in his account to go to a summer camp for artists. What is the total amount of money Benny spent to go to the summer camp? (5 points)
$140.00
$280.00
$420.00
$440.00
Benny deposited $92.50 into his account every month for 10 months, so the total amount he deposited is 92.5 * 10 = $<<92.5*10=925.00>>925.00.
Benny used $36.50 every month to pay for art lessons, so the total amount he spent on art lessons is 36.50 * 10 = $<<36.50*10=365.00>>365.00.
The total amount of money left in Benny's account after 10 months is 925.00 - 365.00 = $<<925.00-365.00=560.00>>560.00.
Benny used 1/2 of the total money left in his account for the summer camp, which is 560.00 / 2 = $<<560.00/2=280.00>>280.00.
Therefore, Benny spent $280.00 to go to the summer camp.
can you explain in human terms
Certainly! Benny deposited $92.50 into his bank account every month for 10 months, so the total amount he deposited in that time is $925.00. He also had to pay $36.50 each month for art lessons, which amounts to a total of $365.00 over the 10 months. After paying for his art lessons, Benny had $560.00 left in his account. Benny decided to use half of that money, which is $280.00, to go to a summer camp for artists. So in total, Benny spent $280.00 to go to the summer camp.

Megan's DVD club membership, which is $8, is deducted automatically from her bank account every month. Which expression shows the total deductions for the year? (5 points)
(−$8) ÷ 12
(−$8) ⋅ 12
(−$8) − 12
(−$8) + 12
The expression that shows the total deductions for the year is (−$8) ⋅ 12. That means the monthly deduction of -$8 is multiplied by 12 months in a year, giving us a total deduction of -$96 for the year.
