Answer 1

`4.50+2.29n\le60`

Step-by-step explanation

We have that Sarah got a $60 gift card to use in Walmart.

This means that everything she can buy cannot be worth more than $60 (i.e. less than or equal to $60).

She buys orange juice for $4.50 and she wants to buy shirts (which cost $2.29 each)

Let n be the number of shirts Sarah wants to buy.

This means that the cost of n shirts is $2.29n.

Recall that she can only spend less than or equal to $60. This means that the sum of the cost of the orange juice and n shirts is less than or equal to $60.

That is:

`4.50+2.29n\le60`

That is the inequality that represents the situation.
