Question

Sally and John are selling tubs of cookie dough for a fundraiser. Sally sells 2 less than 3 times the number of tubs of cookie dough that John sells. She sells 43 tubs of cookie dough in total. Which equation could you use to find the number of tubs that John sold?

A. (3x - 2 = 43)
B. (3x + 2 = 43)
C. (2 - 3x = 43)
D. (3x = 43)

Answer 1

The correct equation to find the number of tubs John sold is 3x - 2 = 43. By solving this simple linear equation, we find that John sold 15 tubs of cookie dough.

Step-by-step explanation:

The equation that could be used to find the number of tubs that John sold is given by Sally's sales, which are 2 less than 3 times John's sales. Sally sells 43 tubs of cookie dough in total. Therefore, we can express this relationship as an equation where x represents the number of tubs John sells:

3x - 2 = 43

To solve for x, we would add 2 to both sides of the equation to isolate the term with x on one side:

3x - 2 + 2 = 43 + 2

3x = 45

Then we would divide both sides by 3 to solve for x:

(3x) / 3 = 45 / 3

x = 15

So, John sold 15 tubs of cookie dough.
