All these ratios people are having trouble with today.

Its pretty easy once you get the hang of it.

So they release 12 grizzly.

We can say 12/x since we dont know the amount of grizzly bears in total.

We can then set 12/x equal to 2/21 and solve for x by using cross multiplication

Jay places $3200 in an investment account earning 4.1% interest compounded weekly. How much money would he have in the account a
jasenka [17]

Answer:

A = $3,926.71

Step-by-step explanation:

Given: Principal (P) = $3200, Annual Rate (R) = 4.1%, Time = 5 years

To find: How much money would he have in the account after 5 years, if he made no deposits or withdrawals during that time?

Formula: A = P(1 + r/n)^nt

Solution: Compound interest is one of the most important concepts to understand when managing your finances. It can help you earn a higher return on your savings and investments, but it can also work against you when you're paying interest on a loan

First, convert R as a percent to r as a decimal

r = R/100

r = 4.1/100

r = 0.041 rate per year,

Then solve the equation for A

A = P(1 + r/n)^{nt}

A = 3,200.00(1 + 0.041/12)^{(12)(5)}

A = 3,200.00(1 + 0.003416667)^{(60)}

A = $3,926.71

Hence, Jay would have $3,926.71 after 5 years is if he made no deposits or withdrawals during that time.
