Dana and Monique are dog groomers. Dana grooms dogs 4 days a week. Monique grooms dogs 5 days a week. They each earn $12.75 per dog they groom. Each day she works, Dana grooms 15 dogs and Monique grooms 10 dogs each day she works. What is the difference in their weekly earnings?

$127.50

Step-by-step explanation:

multiply for dana: 12.75*15 = 191.25 * 4(days)= 765

multiply for monique: 12.75* 10= 127.50* 5(days)=637.50

765-637.50= 127.50

x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x

step-by-step explanation:

last month maria hiked the 5-mile mountain trail a number of times and she hiked the 10-mile canal trail several times. let x represent the number of times she hiked the 5-mile trail, and let y represent the number of times she hiked the 10-mile trail. if she hiked a total of 90 miles, which equation can be used to find the number of times maria hiked each trail? x + y = 90 5x – 10y = 90 90 – 10y = 5x 90 + 10y = 5x
