Question

Rebecca and Megan are shopping at store that sells jewelry, scarves, and purses. The cost of all the items at the store include tax.

Rebecca buys some scarves that cost $5 each and 2 purses that cost $12 each. The cost of Rebecca total purchase is $39. Which equation can be used to find n, the number of scarves that Rebecca buys?

A. 5+24n=39
B 5n+24=39
C (24+5)n=39
D 24*5+n=39

Answer 1

To answer this item, we let n be the number of scarves that Rebecca bought because the number is unknown. The total cost would be the sum of the amount paid for n scarves and 2 purses. The equation would then be,
                                     5n + (12)(2) = 39
Simplifying,
                                      5n + 24 = 39

Thus, the answer is letter B.
