- Write an expression for how much money you will earn if you work h hours.
You will earn 10.10h dollars
Your friend works a different job but makes the same hourly wage as you, plus he receives tips. Write an expression for your friend’s total earnings for a week during which he works n hours and receives a total of $40 in tips. Then, evaluate the expression for n = 10 and explain what that number means.
Your friend will earn [ 10.10n + 40 ] dollars per week....where n is the number of hours he works
If n = 10.....he works 10 hours....and he earns 10.10 * 10 + 40 = $141
Write a single expression for the sum of your earnings for 3 weeks and your friend’s earnings for 2 weeks. You each work r hours per week and our friend receive $40 in tips per week. Simplify the expression.
You will earn 3 * 10.10 r = [30.30 r] dollars for the three weeks
Your friend will earn 2*10.10 r + 40 = 20.20r + 40 for two weeks
- Write an expression to show the difference between your and your friend’s earning for one week: you work h hours, your friend works n hours, and your friend earns t dollars in tips. (Hint: Be sure to consider the fact that you do not know who earns more money
You make 10.10 h dollars per week
Your friend makes [10.10 n + t ] dollars per week
The difference is l 10.10h - (10.10n + t) l dollars.......we need the absolute value bars because we don't know which person earns more
