Shanice is shopping for new clothes. Store A has shirts on sale for $15 and a scarf she wants is on sale for $12.
Store B doesn't have scarves, but it has shirts on sale for $18. Shanice wants to buy shirts at Store A along with the scarf. She wants to know how many she can buy so that the cost is less than or equal to the cost for the same number of shirts at Store B.
Choose the inequality below which best represents the situation, where s is the number of shirts she can buy.
The inequality that represents the situation is:
15s + 12 ≤ 18s
The situation can be represented by the inequality:
$15s + $12 ≤ $18s
where s is the number of shirts she can buy.
Let's break down the given information:
Store A:
- Shirts cost $15 each
- Scarf costs $12
Store B:
- Shirts cost $18 each
- No scarves available
Shanice wants to buy shirts at Store A along with the scarf, and she wants to know how many shirts she can buy so that the cost is less than or equal to the cost for the same number of shirts at Store B.
To determine the inequality that represents the situation, let's consider the cost for the same number of shirts at both stores.
At Store A, the total cost of s shirts and the scarf can be calculated as: 15s + 12.
At Store B, the total cost for the same number of shirts can be calculated as: 18s.
Since Shanice wants the cost at Store A to be less than or equal to the cost at Store B, we can set up the following inequality:
15s + 12 <= 18s
Thus, the inequality that best represents the situation is 15s + 12 <= 18s.
