Rebecca buys some scarves that cost $5 each and 2 purses that cost $12 each. The cost of Rebecca's 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

B 5n+24=39

Step-by-step explanation:

Let n represent the number of scarves that Rebecca buys.

Rebecca buys some scarves that cost $5 each and 2 purses that cost $12 each. This means that he expression for the total cost of n scarves and 2 purses would be

(5 × n) + (2 × 12)

= 5n + 24

The cost of Rebecca's total purchase is $39. Therefore, the equation can be used to find the number of scarves that Rebecca buys is

5n + 24 = 39

3x3 = 9 and 2x2 = 4
