Mr. and Mrs. Galloway are planning to build a new fence around their garden. They are comparing the different measurements for t

Romashka [77]

Answer:

5 1/8 feets

Step-by-step explanation:

Given that:

PLAN A:

Length of post = 4.25 feets

Post must be 7/8 feets below the ground

Height of fence in PLAN A :

Converting 4.25 feets to decimal :

4.25 feets = 4 feets + 0.25 feets

0.25 feets = 1/4 feets

4 + 1/4 feets = 4 1/4 feets

4 1/4 feets + 7/8 feets

17 /4 feets + 7 /8 feets = [(34 + 7) / 8] feets

[(34 + 7) / 8] feets = 41/ 8 feets

41 / 8 feets = 5 1/8 feets

Original price: $125 Discount: ? Sale price: $81.25 Find the discount

Paha777 [63]

Original price=125
discount=x dollars or percent I will find both
sale price=81.25

so origonal-discount=sale
125-x=81.25
subtract 125 from both sides
-x=-43.75
multiply -1
x=43.75
the discount was 43.75

to convert into fraction divide 43.75 by 125 then multiply by 100
43.75/125=0.35
0.35 times 100=35%

35% discount
