Your school is having a fundraiser. You are selling candy bars that have been donated by the Hershey Company. You set a personal goal of raising $200 for your school and met that goal. You sold a total of 120 candy bars and one neighbor gave you a $20 donation without taking any candy bars. Write an equation to determine how much each candy bar sold for.

200=120*x+20

-20         -20

180=120x

x=180/120

x=1.5 $

Step-by-step explanation:

Each candy bar cost $1.5

Step-by-step explanation:

Let x be the price of a candy bar

We have the equation:

120x + 20 = 200

120x = 180

x = $1.5

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

the answer is c.
