Explanation:

The correct question is

Zena needs a salesperson. Salesperson A is offering his services for an initial $50 in addition to $5 per hour. salesperson B is offering her services for an initial $40 in addition to $7 per hour. When will the two coaches charge the same amount of money?

Let

x ----> the number of hours

y ----> the total charge

we know that

Salesperson A

`y=5x+50` ------> equation A

Salesperson B

`y=7x+40` ------> equation B

To find out when the two coaches charge the same amount of money, equate equation A and equation B and solve for x

`7x+40=5x+50`

`7x-5x=50-40`

`2x=10`

`x=5\ hours`
