Question

First, Jorge does inventory on the hamburger patties. On Friday, he had 220 hamburger patties. That evening, 15 guests ordered hamburgers. The next evening, 3 tables of 4 guests also all ordered hamburgers. On Sunday evening, the restaurant was closed but a small delivery truck dropped off a package of 25 hamburger patties. Which equation correctly shows how many hamburger patties Jorge had by Sunday evening?

A. 220 - 15 - (3 * 4) + 25
B. 220 + 15 + (3 * 4) - 25
C. 220 + 15 + (3 * 4) + 25
D. 220 - 15 - (3 * 4) - 25

Answer 1

The right equation to calculate the number of patties Jorge had by Sunday evening is Option A: 220 - 15 - (3 * 4) + 25. These calculations lead to a final total of 218 hamburger patties.

Step-by-step explanation:

To determine how many hamburger patties Jorge had by Sunday evening, we will need to calculate the change in the number of patties over the weekend. Let's look at each day's transactions individually:

• On Friday, Jorge started with 220 patties and 15 were ordered, so he sold 15 patties.
• The next day, 3 tables with 4 guests at each table ordered hamburgers, meaning 3 times 4, which is 12 patties were sold.
• On Sunday, the restaurant was closed but they received a delivery of 25 patties.

To calculate his final inventory, we will subtract the patties sold and add the patties received. Therefore, the equation representing this situation is:

220 - 15 - (3 * 4) + 25

After doing the math:

1. Subtract the 15 patties sold on Friday: 220 - 15 = 205 patties.
2. Subtract the patties sold to the 3 tables: 205 - (3 * 4) = 205 - 12 = 193 patties.
3. Add the delivery of 25 patties received on Sunday: 193 + 25 = 218 patties.

Thus, the correct equation is Option A: 220 - 15 - (3 * 4) + 25, which results in 218 patties.
