Question

You and three friends are buying gift bags. You all agree to spend at most $12 from each person.

A) Write an inequality to express the total amount you all spend

B) Solve the inequality in A

Answer 1

Since there are four people (yourself and three other friends), and each one spends 12 dollars, an appropriate inequality would be \[x\le 4(12)\]The key term "at most" is a signal term for less than or equal to, the "4" represents the amount of people, and the "12" represents the maximum each person is willing to spend.
Solving this, you would multiply 4 by 12 and get \[x\le 48\]
