Three friends share the cost of a pizza. The base price of the pizza is p and the extra toppings cost $4.50. If each person’s share was $7.15, which equation could be used to find p, the base price of the pizza?
7.15 =1/3 P+4.50
or 7.16=1/3 (p+4.50)
ok. this is similar to the last two. No ideas?
yes
yes, no idea, or
yes, here's my idea?
If no idea, look at the last two problems. There must be some first step you could make.
total cost is (p+4.50)
so, the 2nd equation is correct (except for the typo :-))
do you guys tutor
I do some, but usually in person.
There are online sites for finding tutors. WyzAnt is a good one.
wrong
To find the equation that can be used to determine the base price of the pizza, we need to consider the total cost of the pizza. Let's break down the problem:
- The base price of the pizza is p.
- The extra toppings cost $4.50.
Each person's share is $7.15, so the total amount paid by the three friends is (3 × $7.15) = $21.45.
To find the equation, we need to consider the cost of the base pizza and the cost of the extra toppings. The total cost of the pizza can be expressed as the sum of the base price (p) and the cost of the extra toppings ($4.50).
Therefore, the equation to determine p, the base price of the pizza, is:
p + $4.50 = $21.45
