Question

At the beginning of the month, Shiloh made 89 servings of trail mix. By the end of the month, she had 55 servings of trail mix left. Which equation could be used to find x, the number of servings of trail mix that had been eaten during the month?

A.
55 - 89 = x
B.
89 - x = 55
C.
89x = 55
D.
x + 89 = 55

Answer 1

The equation to find
`x`, the number of servings eaten during the month is:

B.
`89-x=55`

Explanation:

Given:

Number of servings of trail mix made by Shiloh = 89

Number of servings of trail mix left by the end of month = 55

To write an equation to find
`x` which is the number of servings eaten during the moth.

Solution:

The total number of servings of trail mix made = 89

Number of servings eaten during the month =
`x`

Servings of trail mix left by the end of the moth can be given as:

⇒
`89-x`

Number of servings actually left by the end of the month = 55

Thus, the equation to find
`x`, the number of servings eaten during the month is:

`89-x=55` (Answer)

On solving for
`x` we get the number of servings eaten.
