Clare’s aunt used a credit card to pay $42 for an outfit. Six weeks later, the credit card company charged her 2% interest. a. How much is the 2% interest?
b. How much will Clare’s aunt have to pay in total?

0.84$ and 42.82$

Step-by-step explanation:

2% is equivalent to 2/100

So, 42$ x = 84/100 = 0.84$ (the 2% interest)

And the total the aunt has to pay equals to = 42$ + 0.84$ =42.84$

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5
