The sum of 5 times a number and 8 is equal to 9

Irina-Kira [14]

Answer:

The unknown number is $\frac{1}{5}$

Step-by-step explanation:

Let's make the unknown number x.

The sum of 5 TIMES a number (x) & 8 is 9.

Let's write it mathematically.

5x + 8 =9

We are trying to find the unknown number, so let's remove all the numbers from the left side to find x. Minus 8.

5x=1

5x is basically 5 times x, so to find x, we need to divide and from there we can remove 5.

x= $\frac{1}{5}$

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.
