Solve leave in simplified form.
ELEN [110]

Answer:

6  service contracts were sold.

Step-by-step explanation:

A salesperson earned $300 a week plus a bonus of $18 for each service contract sold.

Weekly Salary = 300W + 18X

where W = number of weeks and X = number of service contracts sold.

the pay one week was $408 how many service contracts were sold?

Weekly Salary = $408

W = 1 week

408 = 300(1) + 18X

408 = 300 + 18X

408 - 300 = 18X

108 = 18X

108/18 = X

6 = X
