Vi walks 2 miles on first day, 2 miles on second day, 8 miles on third and fourth day and 1 mile on fifth day.
Step-by-step explanation:
Let,
x be the distance walked by Vi.
Therefore,
On first day = x
Second day = x
On days three and four,Vi walks twice as long as on the first two days
Third and fourth day = 2(x+x) = 2(2x) = 4x
On fifth day = half of first day = = 0.5x
Total distance = 13 miles
Therefore,
Dividing both sides by 6.5
Distance on first day = x = 2 miles
second day = x = 2 miles
third and fourth day = 4x = 4(2) = 8 miles
fifth day = 0.5x = 0.5(2) = 1 miles
Vi walks 2 miles on first day, 2 miles on second day, 8 miles on third and fourth day and 1 mile on fifth day.

Let us say, the CD amount she invested is "c"
and the amount she invested in the savings bond is "s"
she invested a total of 5,000
so, whatever "c" is and "s" is, c + s = 5,000
now, the CD account earned 4% in interest
4% in decimal form is 4/100 or 0.04
she also earns 7% from the saving bonds,
7/100 is 0.07
the interest earned after one year are 300
that is, the 4% per year and the 7% per year add up to 300 bucks
so, one can say that
0.04c + 0.07s = 300
and the amount she invested in the savings bond is "s"
she invested a total of 5,000
so, whatever "c" is and "s" is, c + s = 5,000
now, the CD account earned 4% in interest
