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. Homework Help ✎

Write two equations to describe the situation:

$4t=3b$

$5t+6b=8.58$
