A student earns $55 doing errands for their neighbor. They want to purchase a jersey that costs $65. Use a number to represent the amount of money the student will have in their bank account after the purchase?
The student will have -$10 in their bank account after the purchase.
To find the amount of money the student will have in their bank account after purchasing the jersey, we need to subtract the cost of the jersey from the amount of money earned.
Amount earned = $55
Cost of jersey = $65
To find the amount of money the student will have in their bank account after the purchase, we subtract the cost of the jersey from the amount earned:
Amount earned - Cost of jersey = Bank account balance
$55 - $65 = -$10
Therefore, the student will have -$10 in their bank account after purchasing the jersey.
