Question

Nata spent $28 on 2 DVDs. at this rate, how much would 5 DVDs cost? at what rate did she spend her money

Answer 1

Make a proportion:
2/28= 5/x and x would equal the amount of money she has to spend for 5 DVDs.
cross multiply then you'll get:
140=2x
x=70
She would have to pay $70 for 5 dvds. 

Answer 2

5 DVDs would cost $70
