Answer:
100
Step-by-step explanation:
25% of 100=25
100+25=125
125-25=100
It goes up 25% then it gets discounted back down to its original price
(60,58200) , (90,85200)
slope = (85200 - 58200) / (90 - 60) = 27,000/30 = 900
y = mx + b
slope(m) = 900
(60,58200)...x = 60 and y = 58200
sub and find b, the y int
58200 = 900(60) + b
58200 = 54000 + b
58200 - 54000 = b
4200 = b
ur equation is : C(x) = 900x + 4200 <== ur equation
Answer:
7 years
Step-by-step explanation:
Use the formula I=Prt
Convert 4% to a decimal. 4% = 0.04
1428 = 5100(.04)t
1428 = 204t
1428/204 = 204t/204
t = 7 years
Area = length × width
45/4 = 9/2 × width
width = (45/4) ÷ (9/2)
= 5/2 feet
