CPM Homework Help : CCA2 Problem 5-88

On Wednesdays at Tara's Taquería four tacos are the same price as three burritos. Last Wednesday the Lunch Bunch ordered five tacos and six burritos, and their total bill was $\$8.58$ (with no tax or drinks included). Nobody in the Lunch Bunch can remember the cost of one of Tara's tacos. Help them figure it out.

Step 1:

Define two variables: Let $t=$ the cost of a taco and $b=$ the cost of a burrito.

Step 2:

Write two equations to describe the situation:

$4t=3b$

$5t+6b=8.58$

Step 3:

Solve the system of equations and answer the question. Check your work!
