Answer:
Day1 = 23
Day2 = 15
Day3 = 60
Step-by-step explanation:
Three evenings take place and we know that Ashley recives a total of 98 calles. The first evening has eight more calles then day two, so:
Day1 = Day2 + 8
The third evening she recives 4 times the calls from the second evening, so:
Day3 = 4 * Day2
We know the total calls during the three days are as follows:
total = Day1 + Day2 + Day3 , (Note that total = 98)
Sub in Day1 and Day3 into the total equation:
98 = (Day2 + 8) + Day2 + (4 * Day2)
All that is left to do is simplify the linear equation to find Day2:
98 = 6 * Day2 + 8
90 = 6 * Day2
90 / 6 = Day2
15 = Day2
Since we now know Days2, we get the equaiton for Day1 and Day3 and sub in Day2:
Day1 = Day2 + 8 = 15 + 8 = 23
Day3 = 4 * Day2 = 4 * 15 = 60
Double-checking to see if we have the right values by solving the total with all knowns:
total = Day1 + Day2 + Day3
98 = 23 + 15 + 60, which is true
