Problems Involving Algebraic Expressions

Tickets to the aquarium cost $27 per person. Write an expression to represent the total cost of tickets for a group of people. Let n represent the number of people in the group.

• 27 + n

• 27n

• 27/n

• 27 - n

Kelly has some money she has already saved. After mowing two lawns on Saturday, she adds $40 to her savings. How much money has Kelly saved altogether? Let s represent the amount of money she already has in savings.

• s + 40

• 40/s

Tyrell has a sister that is y years younger than him. If Tyrell is 12 years old, how old is his sister? Which algebraic expression could be used to find the age of Tyrell's sister?

• y - 12

• 12 / y

• 12 + y

• 12 - y

Mr. Krabs has 100 more dollars than Squidward. Which equation represents this situation?
Mr. Krabs = K
Squidward = S

• S = 100 + K

• S = 100K

• K = 100S

• K = 100 + S
