Question

Kari is starting a dog walking service and charges a 12% tip for each client. Write an algebraic expression that represents how much of a tip Kari should collect given any amount of service.

a) (0.12s)
b) (s + 0.12)
c) (0.88s)
d) (1.12s)

Answer 1

The algebraic expression for the tip Kari collects for her dog walking service, where she charges a 12% tip on her service charges, is (0.12s).

Step-by-step explanation:

This is asking for an algebraic expression that represents the amount of tip Kari should collect for her dog walking service, given any amount of service charges. The service includes a 12% tip on top of the service charges. Therefore, to find the tip amount, you multiply the service charge (represented by s) by 0.12, which is the decimal equivalent of 12%. Hence, the correct algebraic expression for the tip Kari collects is (0.12s), option a).
