Final answer:
Marcus worked 8 hours for the week and earned $80. In the new position, he will make $182, which is higher than his current earnings. He should take the new position as it offers a higher salary.
Step-by-step explanation:
Marcus can find the answers to his questions by using the information provided in the question. To calculate the number of hours Marcus worked for the week, we need to find the difference between the starting time and the ending time.
Let's say Marcus started working at 9 am and ended at 5 pm. The difference is 8 hours. Therefore, Marcus worked for 8 hours for the week.
To calculate Marcus's earnings for the week, we need to multiply his hourly wage by the number of hours he worked. Let's say Marcus's hourly wage is $10. Multiplying $10 by 8 gives us $80. Therefore, Marcus earned $80 for the week.
Now let's compare Marcus's earnings in the new position to his current job. In the new position, Marcus earns a fixed salary of $150 per week plus a commission of 25 cents for each ice cream cone he sells. On average, Marcus sells 128 ice cream cones each week.
So, we can calculate his earnings by multiplying the number of ice cream cones sold by the commission rate and adding it to his fixed salary. The calculation would be (128 x $0.25) + $150 = $32 + $150 = $182.
Therefore, Marcus will make $182 in the new position. Comparing this to his current earnings of $80, it is clear that Marcus should take the new position as it offers a higher salary.
