I = PRT.....rearrange = I / PR = T
I = 450
R = 7.5%...turn to decimal = 0.075
P = 2400
I / (PR) = T
450 / (2400 * 0.075) = T
450 / 180 = T
2.5 = T...so time is 2.5 years, or 2 1/2 years
Instead use WolframAlpha.com for math questions I would paste the answer but a cretinous fop has "disabled" that feature by javascript -- which is trivial to circumvent but I won't bother with the time.
Answer:
<h2>1.80 per pound of strawberries</h2><h2 />
Step-by-step explanation:
8.10 / 4.5 pounds = 1.80 per pound of strawberries
A = 1/2bh...for h
multiply both sides by 2
2A = bh
now divide both sides by b
(2a)/b = h
