Question

If 2.5 kg of tomatoes cost $8.25, how much will you pay for 7 kg?

Answer 1

$23.10

Explanation:

8.25 ÷ 2.5 = 3.3

7 x 3.3 = 23.10

you have to find out how much money you pay per kg

you pay $3.30 per kg

therefore you have to multiply the kg (7) by the price (3.30) and that's why you get $23.10

hope this helps :)

Answer 2

$2.10

Explanation:

first we want to find for one kg. one kg is $0.30.

Multiply that by 7 and you get $2.10
