Question

- You want to know the number of minutes that you can use on your $25.00 phone card. The card company charges you $0.25 for the first minute and $0.25 for each additional minute. Solve the formula $25.00 = $0.25 + $0.25m for m. Justify each step with an algebraic property of equality.​

Answer 1

hi

0.25m +0.25 = 25

0.25m = 24.75

m = 24.75/0.25

m = 99
