If an 8 oz. can of vegetables cost $1.50, how much would you expect a 21 oz. can of vegetables to cost at the same rate? Please explain please.

Answer:
$3.94
Step-by-step explanation:
What we know:
An 8 oz. can costs $1.50
What we don't know:
How much a 21 oz. can costs
How to solve:
21 ÷ 8 = 2.625
So, multiply 1.5 by 2.625
1.5 · 2.625 = 3.9375
3.9375 ≈ $3.94
Solution:
A 21 oz. can costs about $3.94
