Question

If 3 tacos at taco el primo cost $5.31, how much would 8 tacos cost?

Answer 1

3t = 5.31

t = 1.77

We're looking for 8t.

t = 1.77

8t = 14.16

Answer 2

`\$14.16`

Explanation:

Since the question implies a constant rate, we can set up the following proportion:

`(3)/(5.31)=(8)/(x),\\3x=8\cdot 5.31,\\x=(8\cdot 5.31)/(3)=\boxed{\$14.16}`
