Question

Write the inequality for Sarah wants to spend no more than $50 on Christmas. She can buy her friends shirts for $10 or coffee mugs for $5.

Answer 1

Answer:

10x+5y≤50

Explanation:

Let the number of shirts Sarah buys = x

Cost of a shirt = $10

Therefore, the cost of x shirts = 10x.

Let the number of coffee mugs Sarah buys = y

Cost of a coffee mugs = $5

Therefore, the cost of y coffee mugs = 5y.

The total money spent by Sarah will be:

$10x+5y$

Since she wants to spend no more than $50 on Christmas:

She can spend less than or exactly $50.

Therefore, an inequality representing this is:

$10x+5y\le50$
