Suppose that when your friend was born, your friend’s parents deposited $2000 in an account paying 4.5% interest compounded quarterly. What will the account balance be after 18 years?​

The account balance will be $4475.53 after 18 years.

Step-by-step explanation

Since the inital deposite is $2000, we have 2000 before the parenthases. Then we have 1+ because your friend's parents are Paying interest, which is adding. then we have to convert 4.5% by moving the decimal point over 2 places to the left and adding in zeros. So, 4.5% is now 0.045. then we divide 0.045 by 4 because they are paying quarterly. Finnally we have (4)(18) as an exponent because they are paying 4.5% interest quarterly through 18 years.

So we have

= 4475.53

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
