Sandy bought 12 7/8 pounds of peaches to make jam. She and her mother ate 0.75 of a pound of the peaches before making the jam. They used 9 3/8 pounds of the peaches to make the jam. How many pounds of peaches were left over?

A. 3 1/4
B. 3
C. 2 3/4
D. 2 1/4

Answers

Answer:

C

Step-by-step explanation:

initial amount: 12 7/8 lbs

ate: 0.75 lbs= 3/4 lbs = 6/8 lbs

used: 9 3/8 lbs

remainder: 12 7/8 - 9 3/8 - 6/8

                = 3  1/8 - 3/8

                =2 6/8 = 2 3/4 = C

therefore C is the answer

A local hamburger shop sold a combined total of 613 hamburgers and cheeseburgers on Wednesday. There were 63 more cheeseburgers sold than hamburgers. How many hamburgers were sold Wednesday

Answers

Answer:

This problem can be solved through the creation of a system of equations relating the number of hamburgers (x) and cheeseburgers (y).

 

Having a combined total of 603 hamburgers and cheeseburgers can be written as x+y=603 and having 53 more cheeseburgers than hamburgers can be written algebraically as y=x+53.

 

To solve the system:

x+y=603

y=x+53

 

Substitute what y equals in the second equation for y in the first equation:

x+(x+53)=603

2x+53=603

  -53    -53

2x=550

2    2

x=275 hamburgers

 

To solve for the number of cheeseburgers, substitute 275 for x in either equation.

y=x+53

y=275+53

y=328 cheeseburgers

 

To double check your work, make sure that 275+328=603 and that 328=275+53. Since both are true, you have solved for the number of hamburgers (275) and cheeseburgers (328).

Step-by-step explanation:

Answer: 58 cheeseburgers
