5 per yard, per month. If she provides full landscaping service for four times the number of yards (which she provides mowing alone),and her earnings are $4760 for a month, how many yards does Melissa provide the full landscaping maintenance service for?
Well you have to first find the constant of Brand X which would be 2.70/10 = .27. Brand Y is .4 more so that would be .31 per ounce. So then .31 x 11 = 3.41. The cost of 11 ounces of brand Y is $3.41.
