Answer 1

Answer:

A)She buys 4.5 dozens of hamburger buns

B)Kim spend $15.15 in all

Step-by-step explanation:

A)

Caitlyn buys sandwich rolls = 2.5 dozens

She buys dinner rolls = 1.25 dozens

We are given that She also buys 1.2 times as many hamburger buns as she does sandwich and dinner rolls combined.

She buys no. of hamburgers = 1.2(2.5+1.25)=4.5 dozens

Thus She buys 4.5 dozens of hamburger buns

B)

Cost of 1 pound of american cheese = $4.5

Cost of 1.5 pounds of american cheese =$4.5 \times 1.5 =6.75$

Cost of 1 pound of Swiss cheese = $4.8

Cost of 1.75 pounds of Swiss cheese = $4.8 \times 1.75 =8.4$

Kim spend in all = 6.75+8.4=$15.15

Thus She spend $15.15 in all
