Valerie is ordering salads and drinks for her friends. salads cost $7 each, drinks cost $3 each, and there is a $5 delivery charge per order. she has $50. if she buys 3 salads, how many drinks can she buy?

Respuesta :

Since there is a $5 delivery charge, Valerie will surely spend those money.

Also, since a salad costs $7, and Valerie buys 3 of them, she will spend 21 more dollars.

So, salads and delivery charge sum up to [tex] 21+5 = 26 [/tex]

This means that Valerie has [tex] 50-26 = 24 [/tex] dollars left. A drink costs $3, so she can buy

[tex] \dfrac{24}{3} = 7 [/tex] drinks.
