Answer:

y = 7

Step-by-step explanation:

6y+3=45   (subtract 3 from both sides)

6y = 45 - 3

6y = 42 (divide both sides by 6)

y = 42/6

y = 7

Answer:

y=7

Step-by-step explanation:

To solve the equation, we want to find out what <em>y</em> is. In order to do this, we have to get <em>y</em> by itself. Perform the opposite of what is being done to the equation. Keep in mind, everything done to one side, has to be done to the other.

6y+3=45

3 is being added to 6y. The opposite of addition is subtraction. Subtract 3 from both sides.

6y+3-3=45-3

6y=45-3

6y=42

6 and y are being multiplied (6*y=6y). The opposite of multiplication is division. Divide both sides by 6.

6y/6=42/6

y=42/6

y=7

Let's check our solution. Plug 7 in for y in the original equation.

6y+3=45

y=7

6(7)+3=45

42+3=45

45=45

Both sides of the equation are the same, so we know our solution is correct.

The formula of the future value of an annuity ordinary is
Fv=pmt [(1+r)^(n)-1)÷r]
Fv future value?
PMT 2400
R 0.08
T 32 years
Fv=2,400×((1+0.08)^(32)−1)÷(0.08)
Fv=322,112.49
Now deducte 28% the tax bracket from the amount we found
annual tax 2,400×0.28 =672 and tax over 32 years is 672×32 =21,504. So the effective value of Ashton's Roth IRA at retirement is 322,112.49−21,504=300,608.49
