Question

writ an equation that models the situation and find its solution. it going to be sam's birthday soon, and her friends joe, carly, jessica and shane have contributed equal amounts of money to buy her a present. they have $25.00 to spend between them. determine how much each contributed.

Answer 1

hello

the number of friends contributing money = 4

since they contributed equal amount of money, the total amount they contributed = 4x

the total amount they contributed amongst them = $25

the amount each individual contributed = x

to find the amount each contributed, let's equate the amount contributed to 4x

$\begin{gathered} 4x=25 \\ \text{divide both sides by 4} \\ \frac{4x}{4}=\frac{25}{4} \\ x=6.25 \end{gathered}$

Sam's friend contributed $6.25 amongst them equally to give a total of $25
