Answer:

22.75 applications

Step-by-step explanation:

From the above question, we understand that:

4 -oz bottle = 7 applications

13 -oz bottle = x applications

Cross Multiply

4 -oz bottle × x applications = 13 -oz bottle × 7 applications

x applications = 13 -oz bottle × 7 applications/4 -oz bottle

x applications = 22.75 applications

Therefore, the number of applications of the 13 -oz bottle self-tanner that should Jen expect is 22.75 applications.

The number of applications that Jen can expect from the self-tanner is 22.75 applications.

The first step is to determine how many applications 1 -oz of the bottle can provide.

Number of applications 1 -oz of the bottle can provide = 7/4 = 1.75

The second step is to multiply the figure gotten in the previous step by 13

13 x 1.75 = 22.75 applications
