3. Red candy costs $2.50 per pound. Green candy costs $4.75 per pound. You bought ten pounds of candy for $38.50. How many pound
Aloiza [94]

Answer:

6 pounds of green candy

Step-by-step explanation:

Let r be the weight of red candy

Let g be the weight of green candy

Total weight = 10 pounds

r + g = 10 -------------------------(I)

Total cost = $ 38.50

2.50r + 4.75g = 38.50  --------------(II)

Multiply equation (I) by -2.50

(I)* (-2.50)             -2.50r - 2.50g = -25.0

(II)                          <u>2.50r + 4.75g = 38.50 </u>   {Now add and r will be eliminated}

                                        2.25g = 13.50

g =13.50/2.25

g = 6

Plug in the value of g in equation (I)

r + 6 = 10

r = 10 - 6

r = 4

Jennifer planted a tree that was 0.17 of a meter tall. After 10 years, the tree was 100 times as tall as when she planted it. Wh
Travka [436]
To solve, you need to carry the decimal two spaces to the right because there are two zero in 100 so 0.17 times 100 is 17.  The height of the tree after ten years was 17 meters tall in height.

Dylan is going to invest $360 and leave it in an account for 5 years. Assuming the interest is compounded quarterly, what intere
Lilit [14]

The rate of interest at which Dylan invested is 3.09%.

The practice of adding interest to the principal of a loan or deposit is known as compound interest, sometimes known as interest on principal and interest. It happens when interest is reinvested, added to the collateral for the loan rather than paid out, or when the borrower is forced to pay it, resulting in interest being created on the principal amount plus any accumulated interest the following period. Compound interest is a prominent concept in finance and economics.

Compound interest allows interest to accumulate over time, in contrast to simple interest, which does not compound because past interest is not returned to the principle for the present period.

principal =360

time =5 years

n=5×4=20 (compounded quarterly)

Amount = 420

Now: 420 = 360(1+r)²⁰

solving for r we get:

r= 0.007737

required rate percent = 0.007737×4 = 0.00193 × 100 = 3.09%

hence the simple annual interest rate is obtained by multiplying the interest per period by the total number of periods in a year is 3.09%.
