Answer:
Part a: $10h + $15s ≤ $55
Part b: She can buy 3 shirts
Step-by-step explanation:
Part a: Write an equation to model the situation
Stephanie has $55 to spend. Assume that hats are h, and shirts are s.
She can buy h hats for $10 each, represented as $10h
She can s shirts for $15 each, represented as $15s
She cannot spend more than $55
So that means $10h + $15s ≤ $55
It has to be less than or equal to because she can spend less money or $55 on her brother.
Part b: if she buys 1 hat, how many shirts can she buy?
Lets use our equation from part a
$10h + $15s ≤ $55
replace for for h because she bought 1 hat
$10 + $15s ≤ $55
Solve:
$10 + $15s ≤ $55
$15s ≤ $45
s ≤ 3
She can buy 3 shirts
