Answer:
You can use the sponge 22 times to create the design
Step-by-step explanation:
Area of the parallelogram-shaped sponge = base × height = 3 inches × 1 inch = 3 square inches
Area of design = 66 square inches
Number of times to use the sponge to create the design = Area of design ÷ Area of parallelogram-shaped sponge = 66 square inches ÷ 3 square inches = 22
The sponge can be used 22 times to create the design
Answer:
let F=fee; R=hourly rate=1.2F ; N=number of hours
Total charge=F+NR
Total charge=F+N(1.2F)
$470=F+7(1.2F)
$470=F+8.4F
$470=9.4F
$50=F ANSWER 1: Her fee is $50
