<em><u>Question:</u></em>
Ana participated in a charity walk. She raised $0.25 for each 1/2 mile that she walked.The first day Ana walked 11 miles.The second day, she walked 14 miles.How much money did Ana raised?
<em><u>Answer:</u></em>
Ana raised $ 12.5
<em><u>Solution:</u></em>
From given question,
First day walk = 11 miles
Second day walk = 14 miles
<em><u>Let us first calculate the total distance she walked</u></em>
Total distance = first day walk + second day walk
Total distance = 11 + 14 = 25 miles
Thus she walked for 25 miles
Given that,
<em><u>She raised $0.25 for each 1/2 mile that she walked</u></em>
Therefore, for 1 mile we get,
Now calculate for 25 miles
Thus she raised $ 12.5
A + 3(a -1) - 5a
Simplify.
a + 3a - 3 - 5a
Add like terms.
(a + 3a - 5a) + (-3)
Simplify.
(4a - 5a) - 3
-a - 3
