Question

A bank charges a monthly fee of $5.00 for using a debit card. In addition, the bank charges $0.25 for each transaction made with the debit card. If you pay the bank a total of $15.00 one month for using your debit card, how many transactions did you make in that month? Equation: 5 + 0.25x = 15

Answer 1

To solve you would first subtract the five from both sides:
0.25x = 10
Then you would divide 10 by 0.25 or 1/4 which would be the same thing as multiplying by 4:
x=10(4)
So the answer is x= 40

Answer 2
