Question

Mohamed, Amir, and Vedant go out to lunch. They each buy a cheeseburger and a soda. The soda costs $1.75 each. If the total cost for their meals is $19.50, how much did each cheeseburger cost?Choose the equation that best represents this situation.

A.) 3n + 1.75 = 19.50
B.) 3n + 19.50 = 1.75
C.) 3(n + 1.75) = 19.50
D.) n(3 + 1.75)= 19.50

Answer 1

The equation that represents this situation is 3(n + 1.75) = 19.50. To find the cost of each cheeseburger, we can solve this equation for n. Therefore, each cheeseburger costs $4.75.

Step-by-step explanation:

The equation that represents this situation is 3(n + 1.75) = 19.50.

To find the cost of each cheeseburger, we can solve this equation for n. First, we distribute the 3 to the terms inside the parentheses, giving us 3n + 5.25 = 19.50. Next, we can isolate the 3n term by subtracting 5.25 from both sides, resulting in 3n = 14.25. Finally, we divide both sides by 3 to solve for n, giving us n = 4.75.

Therefore, each cheeseburger costs $4.75.
