I think the correct answer is D
[deleted due to wrong answer]
Distance = rate x time
D = 450 mph x 2.5 h
D = 1,125 miles
Flower bed A:
circumference= 2 x pi x r= 2x pi x10/2
=10pi feet
Area= pi x r^2=25pi square feet
Flower bed B:
circumference=12 pi feet
Area=36 pi square feet
So to find percent increase, you want to minus the difference in cost..
1.09- 0.87= .22...
now divide the difference by the original....
.22 ÷ .87 = .25287.....etc
now multiply that by 100...
.25287 × 100 = 25.287
now it says round to the nearest tenth so...
25.29% increase.
