Question 717627: Jake is taking four of his friends to dinner. At the restaurant, a meal, side item, dessert, and drink cost $5.91. The first drink is included with the meal, but each refill costs $0.65. (Assume these prices include tax.)
If Jake doesn't want to spend more than $38.00 on the meal, excluding tip, which of the following inequalities can be used to find r, the number of refills Jake and his friends can have?
Answer by jndarrell(58)   (Show Source):
You can put this solution on YOUR website! You have 5 total people eating at a cost of $5.91 per person. (5*5.91=29.55)
Knowing your budget is $38.00, take off the meal price $29.55. (38-29.55=8.45)
You have $8.45 remaining to spend on refills. Knowing each costs $0.65, you can find how many of those can be ordered.
(8.45/0.65=13)
The finality of this all is that after Jake pays for initial dinner combos for himself and 4 friends, he has enough money left to buy an additional 13 refills without going over his $38.00 spending limit.
r=13 refills
