If Emily bikes 10 miles, how much will her mother donate?

Answer 1

`\$4`

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 :)

Answer 2

Answer: $4

Explanation:

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

`(0.20)/(x ) = (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.
