Explanation:

Question 16: Which is the better deal?

Step 1: Calculate unit price for Save On

To find the unit price (price per apple) for Save On, we divide the total price by the number of apples. The formula for unit price is $\text{Unit Price} = \frac{\text{Total Price}}{\text{Number of Apples}}$. For Save On, we have 4 apples for $2.30. So, the unit price is $\frac{2.30}{4} = 0.575$ dollars per apple.

Step 2: Calculate unit price for Coop

For Coop, we have 6 apples for $3.10. Using the same unit price formula, the unit price is $\frac{3.10}{6} \approx 0.5167$ dollars per apple.

Step 3: Calculate unit price for Safeway

For Safeway, we have 10 apples for $5.10. The unit price is $\frac{5.10}{10} = 0.51$ dollars per apple.

Step 4: Compare unit prices

Now we compare the three unit prices:

• Save On: $0.575$ dollars per apple
• Coop: $\approx 0.5167$ dollars per apple
• Safeway: $0.51$ dollars per apple

The lowest unit price is at Safeway, so Safeway has the better deal.

Step 1: Calculate Tommy's hourly wage

To find Tommy's hourly wage, we use the formula $\text{Hourly Wage} = \frac{\text{Total Earnings}}{\text{Hours Worked}}$. Tommy earned $967 in 38 hours. So, his hourly wage is $\frac{967}{38} \approx 25.447$ dollars per hour.

Step 2: Calculate Sally's hourly wage

For Sally, she earned $417 in 17 hours. Using the same formula, her hourly wage is $\frac{417}{17} \approx 24.529$ dollars per hour.

Step 3: Find the difference in hourly wages

To find how much more Tommy makes per hour than Sally, we subtract Sally's hourly wage from Tommy's hourly wage. So, $25.447 - 24.529 \approx 0.918$, which rounds to approximately $0.92$ dollars per hour.

Answer:

a. Safeway
