Question

Make Sense and Persevere: Beth, Manuel, and Petra are collecting sponsors for a walk-a-thon. The equation У» 20х гергеsents the amount of money Beth raises for walking x miles. The table shows the relationship between the nитber of miles Manuel walks and the атоunt of moпey he will raise. Petra will earn $15 for еach mile that she walks.

a. In order to сompare the prорortional relationships, what quantities should you use to find the unit rate?
A. The number of miles walked
B. The amount of money raised
C. The time taken to walk the miles
D. The sponsors' names

Answer 1

To compare the proportional relationships, use the number of miles walked and the amount of money raised to find the unit rate. For Beth, the unit rate is $20 per mile. For Manuel, create a table to show the relationship between miles walked and money raised. For Petra, the unit rate is $15 per mile.

Step-by-step explanation:

To compare the proportional relationships, you should use the quantities of The number of miles walked and The amount of money raised to find the unit rate. The unit rate is the amount of money raised per mile walked.

For Beth, the unit rate is given by the equation У» 20х, where she raises $20 for each mile walked.

For Manuel, you can create a table showing the relationship between the number of miles walked and the amount of money raised. For example, if Manuel walks 3 miles, he would raise $60 (3 * $20).

For Petra, the unit rate is $15 for each mile walked.
