Answer:
Explanation:
If a kilogram of sweet potatoes costs 25 cents more than a kilogram of tomatoes and 3 kilograms of sweet potatoes cost 12.45 you need to divide 12.45 by 3 to get the cost of 1 kilogram of sweet potatoes.
12.45/3=4.15
We then subtract 25 cents from 4.15 to get the cost of one kilogram of tomatoes because a kilogram of sweet potatoes costs 25 cents more.
4.15-.25=3.9
A kilogram of tomatoes costs 3.90$.
