Answer:
10
Explanation:
We are given that
Devin paid for a membership of the fox lake gym=$30
Devin costs him per class=$2
Jared costs him =$5
We have to find that how many classes would it take for Devin's total cost to equal Jared total cost.
Let x be the number of classes that it would take for Devin's total cost equal to Jared total costs.
Devin's total cost=2x+30
Jared total cost=5x
According to question
![2x+30=5x](https://img.qammunity.org/2020/formulas/mathematics/middle-school/iythctswgo8hwilncjhxc6kare63nn2bm5.png)
![5x-2x=30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/rzmh39jvxgjcfy5srqod0dd0637h3a7w0z.png)
![3x=30](https://img.qammunity.org/2020/formulas/mathematics/middle-school/j0krrjylqsvhfvcfs8cy21dawayewvlveh.png)
![x=(30)/(3)=10](https://img.qammunity.org/2020/formulas/mathematics/middle-school/aef4r3r8zpyeqctewetx0osjo756yfqtxd.png)
Hence, Devin's total cost equal to Jared total cost if they would take 10 classes.
