Odette deposited $3,624.40 into a savings account with an interest rate of 2.1% compounded annual. about how long will it take for the account to be worth $7,000? a. 31 years, 9 months b. 30 years, 9 months c. 28 years, 4 months

7000 = 3624*(1+0.21)^x

7000 = 3624 *1.021^x

7000/3624 = 1.021^x

875/453 = 1.021^x

xlog(1.021 = log(875/453

x = 31.677

for the points! : )

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.
