Question

Sabrina can spend at most $5, including tax, to buy 3 cards. She finds 2 cards priced at $1.25 each and 1 card priced at $1.99, not including tax. Which inequality could be used to determine the amount of money, in dollars, Sabrina can afford to spend on tax (x) when she buys the 3 cards?

2(1.25+1.99)−x≥5

2(1.25+1.99)−x≤5

2(1.25)+1.99+x≤5

2(1.25)+1.99+x≥5

Answer 1

2(1.25)+1.99+x≤5

Explanation:

Because it says "at most $5" that means it would be either 2(1.25+1.99)−x≤5

or 2(1.25)+1.99+x≤5, which narrows it down to two. The reason it is the second option is because she is only buying two cards that cost $1.25, hence this part of the equation: 2(1.25) +1.99+x≤5.
