Suppose she works c hours at the cafe, and m hours at the market.
To earn at least $800, we need
10c + 8m >= 800
60 hours at the market means $480
at most 90 hours per month means at most 30 hours at the cafe, for $300
If you have trouble with the graphs, google graphing inequalities for examples. Or, heck, study your text...
"A student with two summer jobs earns $10 per hours at a cafe and $8 per hour at a market. The student would like to earn at least $800 per month."
a. write and graph an inequality to represent the situation. Include clear labels on the graph.
b. The student work at the market for 60 hours per month and can work at most 90 hours per month. Can the student earn at least $800 each month?
