Question

Mary and Roberto go to the movies. They buy a large popcorn for $8.50, and two medium sodas for $4.25. How much did they spend altogether, if there was a 7.89% tax? Create two equations to solve

Answer 1

Answer:

$19.15

Step-by-step explanation:

Equation 1: 8.50+4.25+4.25= 17.00  (price of the popcorn and drinks)

Equation 2: 17.00/7.89= 2.15                       (how to find how much the tax is)

Solve: 17.00+2.15=19.15                     (add the tax to how much the popcorn and drinks were)
