Question

w much will her mother donate?Emily is entering a bicycle race for charity. Her mother pledges $0.20 for every 0.5 mile she bikes. If Emily bikes 10 miles, how much will her mother donate?

Answer 1

Answer: $4

Step-by-step explanation:

In this situation let's set up a proportional relationship .

$\frac{0.20}{x } = \frac{0.5}{10}$     Now solve by cross multiply  

0.5x  = 2      Divide both sides by 0.5  

x = 4  

This means that if Emily bikes 10 miles, her mother will donate $4.

Answer 2

Answer:

$\ 4$

Step-by-step explanation:

Number of $0.5$ miles in $10$ miles = $10$÷$0.5$

= $20$

Amount of money donated = $0.20$ × $20$

= 4

$\therefore$ Emily's mother donated a total of $\ 4$ given that Emily biked for 10 miles.

Hope this helps :)
