Question

The sports boosters club is having a bake sale to buy uniforms. They want to raise $250. They need to rent a booth for $20. How many dozen cookies will they need to sell if they charge $3 per dozen?
Which equation could be used to solve this problem?

250 = 3c - 20
250 = 3 - 20c
250 = 20 - 3c
250 = 20c - 3

Answer 1

Answer:

250 = 3c - 20

Step-by-step explanation:

They have a goal to raise $250...  but on top of that they will also need to pay $20 for the booth... that has to be covered by the cookies sales too, ensuring they have a net balance of $250 at the end.

So, with 250 = 3c - 20, they will cover that booth expense.

But how many dozens of cookies do they have to sell to reach their goal?

250 + 20 = 3c

270 = 3c

c = 90

They need to sell 90 dozens.  Got milk? :-)
