Question

Emma bought a pair of earrings, a dress and a coat. The dress cost 6 times as much as the earrings, and the coat cost 13 times as much as the earrings. If the three items cost a total of $3200, how much did each of them cost?

Answer 1

Answer:cost of earring=$160

cost of dress= $960

cost of coat =$2,080

Explanation:

Let cost of earring be represented as x

so that the cost of dress =6x

And the cost of coat =13x

Since the three items cost a total of $3200, we can develop an equation which can be represented as

cost of earring+cost of dress +cost of coat =3200

x +6x+13x=3200

20x =3200

x=3200/20=160

THerefore cost of earring=$160

cost of dress= 6x =$160 x 6=$960

cost of coat = 13x = $160 x 13=$2,080
