Question

The high attendance at this year's Vacation Bible School at Highland Church was one hundredseven children. This was twenty-three less than twice the number that attended last year. How manychildren attended last year

Answer 1

65 children

Explanation

Let x = attendance of the last year

Then, twice the number that attended last year is equivalent to 2x

And twenty-three less than twice the number that attended last year is equivalent to 2x - 23

Therefore, this year's attendance, 107 children, is equal to:

`107=2x-23`

Solving for x:

`\begin{gathered} 107+23=2x-23+23 \\ 130=2x \\ (130)/(2)=(2x)/(2) \\ 65=x \end{gathered}`
