Simple interest:

i = prt

where i = interest earned

p = principal deposited

r = annual rate

t = number of years

You want the interest to be $500. The rate is 4%, and the principal is $2000.

Enter those values in the formula for simple interest above and solve for t, the time in years.

500 = 2000 * 4% * t

500 = 2000 * 0.04 * t

500 = 80t

t = 6.25

Answer: 6.25 years

12) You can exchange $5 US dollars for L123 Honduran Lempiras. How many dollars can you exchange L2,300 for? ----​
Anit [1.1K]

Step-by-step explanation:

$5 US dollar = L123 Honduran Lempiras

L2300Honduran Lempiras = x ( Let $ be x)

By using chain rule, we get

5×2300 = 123×x

or, 11500 = 123x

or, x = 11500÷123

hence, x = 93.49593496

The sale price of every item in a store is 85% of its usual price.
Vladimir [108]

Answer

a. The backpack is $4.50

b. The sweatshirt is $2.70

Step-by-step explanation:

a. 30 x 0.15 = 4.50 (The 0.15 is from the price you are actually paying for the item. Because the item is 85% off, you are paying for 15% of the usual price. 15% as a decimal is 0.15 so you multiply that to the original price to find the amount u will pay.)

b. 18 x 0.15 = 2.70

X=17-4y<br> y=x-2<br> answer by substitution
sashaice [31]

Answer:

x=5,y=3

Step-by-step explanation:

the first step is to decide whether you want to substitute y and find x, or substitute x and find y.

(it doesn't matter which way you will choose.If you do the math correctly you will get the correct answer,one way or another).

for example, let's substitute y into the first equation:

x=17-4*(x-2)

so now,we will organize the equation:

x+4x=17+8

5x=25/(÷5)

x=5

now we will substitute x with 5 in the second equation(or the first one,it doesn't matter)in order to find y:

y=5-2

y=3
