Answer:
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
