Answer:

_______

7x + 2 = 5

_______

Step-by-step explanation:

_______________

Two more than the product of A NUMBER and 7 is equal to 5.

That “a number” we can assume is x.

_______________

Two more than the PRODUCT OF (x) AND (7) is equal to 5.

So far, we have x. The sentence says “product of x and 7” which we can translate to 7x

_______________

TWO MORE THAN (7x) is equal to 5.

So that tells us to ADD 2 to (7x) >>> (7x + 2)

_______________

(7x+2) IS EQUAL to 5.

This tells us:

7x + 2 = 5

Goryan [66]

Answer:

She needs to invest $13,636.36 right now

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

$E = P*I*t$

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

$T = E + P$

In this question:

In 15 years, so $t = 15$

She wants to have $30,000, so $T = 30000$

8% interest, so $I = 0.08$

We have to find P.

$T = E + P$

$30000 = E + P$

$E = 30000 - P$

Replacing:

$E = P*I*t$

$30000 - P = P*0.08*15$

$30000 - P = 1.2P$

$2.2P = 30000$

$P = \frac{30000}{2.2}$

$P = 13636.36$

She needs to invest $13,636.36 right now

Answer:

Step-by-step explanation:

Growth can be represented by the equation $A=A_01.02^{t}$ . We know that r=2% or 0.02 in this situation so we have 1.02. We know t=100 hours and the starting population A=200. We substitute these values and use a calculator to evaluate.
