Allushta [10]

Answer:

2.5 %  

Step-by-step explanation:

The simple interest formula is

I = Prt

Data:

I = $75

P = $600

t = 5 yr

Calculation:

75 = 600 × r × 5

75 = 3000 r

Divide each side by 3000

r = 75/3000 = 0.025 = 2.5 % APR

The annual percentage rate is 2.5 %.

The ratio of green pepper plants to red pepper plants in Joe's garden is 2:7. If Joe has 20 more red pepper plants than green pe
Marta_Voda [28]
I found that Joe has 28 red pepper plants and 8 green pepper plants.

to find this, I first set up a proportion:
7/2 = (20+x)/x

then you cross multiply giving you:
7x = 40 + 2x

Subtract 2x from both sides:
5x = 40

solve for x:
x = 8 (which is the amount of green pepper plants)

to find how many red pepper plants he has, plug in x for (20 + x) giving you 28 red pepper plants

Hope I helped :)
