Question

From June to the end of September, Jennifer wants to save at least $1,500. Her monthly expenses are $600. Jennifer saves whatever money she has left after paying her expenses each month. Jennifer is scheduled to work 80 hours in September. Find the minimum sales she needs in September to meet her goal of saving at least $1,500. Show or explain your work for each step.

Answer 1

money left=money earned - expenses

money earned=80*x, x is hourly pay rate

b) money left>=1500, the money left must be eith or over $1500.

expenses=600

plug variables and numbers into money left equation

money left=80x - 600

plug 800x - 600 into inequality b)

800x - 600>=1500

Solve for x

800x - 600>=1500

+ 600>=+600

800x>=2100

x>=2100/800

x>=2.625

If hourly rate of pay must be at least $2.63 per hour.
