james is at a gift sale where everything cost $4(tax included) James has $50. James must have at least $28 remaining when he is finished buying gifts. What is greatest number of gifts James can buy?

Answer 1

Answer: 5

This would be a simple inequality equation.

If everything costs exactly $4 (assuming tax is included in that price), then we know that $4 times the amount of gifts James buys would equal how much money he spends. If he has $50, and he must have at least $28 remaining, then we can ascertain that he can spend $22 by taking $50-$28=$22.

Now we set up the equation with this information.

Let x=the number of gifts James can buy

4x≤22 Divide by 4.

x≤5.5

Since we know James cannot buy 1/2 a gift, he can at least buy 5 full gifts and not spend over $22. Therefore your answer is 5.
