Phil is going to store to buy a hat and a coat. The coat cost 3 times as much as the hat. His mom tells him that he cannot spend more than $120. What is the most he can spend for the coat?

Step-by-step explanation:

Phil is going to store to buy a hat and a coat.

Let $x represent the cost of the cos of the hat. The coat cost 3 times as much as the hat. It means that the cost of the coat will be 3*x = $3x

His mom tells him that he cannot spend more than $120. Assuming he spends exactly $120. It means that

3x + x = 120

4x = 120

x = 120 / 4 = 30

The hat costs $30

The coat costs 30*3 = $90

The most he can spend on a coat is $90 since he cannot spend more than $120
