You owe $225.45 on your credit card. You make a $55.00 payment on your credit card, and then purchase $87.98 worth of clothes at
zubka84 [21]

Answer:

The balance amount owed on the credit card altogether =  $258.43

Step-by-step explanation:

Here, the current amount owed on the credit card = $225.45

Now, the amount of payment made to the credit card  = $55.00

So, the remaining amount owed =   Current Debt - Paid Amount

                                                         = $225.45  - 55 = $170. 45

Again, the purchase amount at Macy's  = $87.98

⇒ New amount owed on credit card  = Previous Debt + New Purchase

                                                                = $170. 45 +  $87.98 =  $258.43

Hence, the balance amount owed on the credit card  =  $258.43

Basically all you’re doing is plugging in the inputs to the equations and see if they’re correct.

5(3)+4(-3)=3 this proves to be true
2(3)-5(-3)=21 not 19
