Question

Pamela sells bracelets for $4.50 each. Last month, she had to spend $25 for materials. Write, solve, and check an equation to show how many bracelets Pamela sold if at the end of the month she had $101 left.

Answer 1

To solve this problem first we hace to name the variable so y will be the earnings and x will be the number of bracelets she sell so the equation will be:

$y=4.50x-25$

So if y is equal to 101 we can solve the equation for x so:

$\begin{gathered} 101=4.50x-25 \\ 101-25=4.50x \\ \frac{76}{4.50}=x \\ 16.88=x \\ 17\approx x \end{gathered}$
