Question

Genevieve collected pledges of $3.50 for every complete mile she runs in a charity race. Her goal is to raise at least $50.00. Genevieve wrote the inequality 3.5m ≥ 50 to find out how many miles she needs to run.

Genevieve thinks she needs to run at least 14 miles.

But Carla says Genevieve needs to run more miles than that.
Who is correct and why?

A.
Carla is correct because 3.5 × 14 is less than 50.


B.
Genevieve is correct because 3.5 × 14 is about 50.


C.
Carla is correct because 3.5 × 14 is not equal to 50.


D.
Genevieve is correct because 3.5 × 14 is greater than 50.

Answer 1

Answer:

A.

Carla is correct because 3.5 × 14 is less than 50.

Step-by-step explanation:

3.5m ≥ 50

To determine how many miles she needs to run, divide each side by 3.5

3.5m/3.5  3.5m ≥ 50 50/3.5

m ≥ 14.28571429

She must run more than 14 miles

Carla is correct because 14* 3.5 = 49.  That is less than the 50 she wants to raise.
