Problema Solution
A couple does not wish to spend more than $90 for dinner at a restaurant. If a sales tax of 4% is added to the bill and they plan to tip 20% after the tax has been added, what is the most they can spend for the meal? (Round your answer to the nearest cent.)
Answer provided by our tutors
let 'x' represent the amount spent on the meal, we require:
90 >= x + 0.04x + 0.20(x+0.04x)
solving, we have:
x <=72.11
they should not spend more than $72.11 for the meal
