Answer:
A) 7p+15
Step-by-step explanation:
To first start things off, we know she automatically has a fee of 15 dollars. No matter what, she must pay the 15 dollars!
Using this information, we know that so far we have: 15+
We also know that it costs 7 dollars for one pizza. If Mrs. Carter decides to buy more then just one pizza then how will we express it? We can express by writing 7x. The reason we have a x with the 7 is because x is the total amount of pizzas.\
Now we combine what we have.
15+7x= the total amount of dollars for x pizzas bought!
I hope this helps! :)
(Side Note: if she gets 2 pizzas you plug in 2 for x.)
