Question

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 she just makes sundaes for a single shift of at most 4 hours and at least 2 hours, which function relates her earnings to the number of minutes she works?

Answer 1

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 $2\leq t\leq 4$

Minimum sundae she makes would be = $\frac{2(120)}{2} =120$

Maximum sundae she makes would be =$\frac{4(120)}{2} =240$

Earnings is 1.20 for each sundae

Thus her earnings would lie between

$1.20(120) to 1.20(240)\\= (14.40, 28.80)$

Answer 2

2 minutes = 1.20 dollars for price of sundae.in 4 hours how many minutes are there?=> 60 * 4 hours = 240 minutes => 240 / 2minutes per sundae = 120 minutes => 120 * 1.20 = 144 dollars in 4 hoursOr 72 dollars in 2 hours
