<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
Slope formula -- y1-y2 over x1 - x2 = -5
Answer:
2
Step-by-step explanation:
This is a linear function, written in the form y=mx+b, where m is the slope, or how many dollars each ticket costs in the case, and b is the initial value of the function, or in this case the cost before any tickets are added to the account.
Since 4x is the slope (4 times however many tickets one purchased), 2 is the initial value before we buy tickets.
You can also plug in 0 for x and get

Answer:
-538.67 (2 d.p)
Step-by-step explanation:
4x +1612 = x - 4
4x -x = -1616
x = (-1616)÷3= -538.67 (2d.p)
