Shirley has a credit card that uses the previous balance method the opening balance of one of her 30 day billing cycles was $283
0 but that was her balance for only the first two days of the billing cycle because she’s been paid off the entire balance and didn’t make any new purchases if your credit cards APR is 19% which of these expressions can be used to calculate the amount Shirley was charged interest for the billing cycle
First you have to multiply the 0.6 of the small shakers times two which gives us 1.2 the amount of salt of the large shakers. divide the 18.6 by 1.2 which is 15.5 the amount going into the 8 shakers. Then subtract 15.5 from 18.6 which gives us 3.1. Then you divide that by 0.6 = 5. 5 small shakers can be filled with the remaining salt.
