Answer:
Step-by-step explanation:
Given that Marge runs an ice cream parlor. Her specialty is triple chocolate sundaes. She can prepare 1 sundae every 2 minutes, and she earns $1.20 for each sundae she makes.
If t is the no of hours she works,
then [tex]2\leq t\leq 4[/tex]
Minimum sundae she makes would be = [tex]\frac{2(120)}{2} =120[/tex]
Maximum sundae she makes would be =[tex]\frac{4(120)}{2} =240[/tex]
Earnings is 1.20 for each sundae
Thus her earnings would lie between
[tex]1.20(120) to 1.20(240)\\= (14.40, 28.80)[/tex]
