Mathematics

Answer:

Step-by-step explanation:

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

A = future value ($)

P = principal (orignal amount - $400)

R = rate (written as a decimal - 3%/100= 0.03)

N = compound (yearly - 1)

T = number of years (0, 5, 10, 15)

Now, substitute each number into the formula and record them in the table.

0 years:

A=P(1+\frac{r}{n})^{nt}\\\\A=400(1+\frac{0.03}{1})^{1*0}\\\\A=400(1+\frac{0.03}{1})^0 < ==any\ number\ raised\ to\ zero=1\\\\A=400(1)\\\\A=\$400

5 years:

A=P(1+\frac{r}{n})^{nt}\\\\A=400(1+\frac{0.03}{1})^{1*5}\\\\A=400(1+\frac{0.03}{1})^{5}\\\\A=400(1+{0.03})^{5}\\\\A=400({2.03})^{5}\\\\A=400({1.1593})\\\\A=\$463.72 < ==round\ to\ the\ nearest\ dollar\\\\A=\$464

10 years:

A=P(1+\frac{r}{n})^{nt}\\\\A=400(1+\frac{0.03}{1})^{1*10}\\\\A=400(1+\frac{0.03}{1})^{10}\\\\A=400(1+{0.03})^{10}\\\\A=400({1.03})^{10}\\\\A=400({1.3439})\\\\A=\$537.56 < ==round\ to\ the\ nearest\ dollar\\\\A=\$538

15 years:

A=P(1+\frac{r}{n})^{nt}\\\\A=400(1+\frac{0.03}{1})^{1*15}\\\\A=400(1+\frac{0.03}{1})^{15}\\\\A=400(1+{0.03})^{15}\\\\A=400({1.03})^{15}\\\\A=400({1.5579})\\\\A=623.16 < ==round\ to\ the\ nearest\ dollar\\\\A=\$623

20 years:

 A=P(1+\frac{r}{n})^{nt}\\\\A=400(1+\frac{0.03}{1})^{1*20}\\\\A=400(1+\frac{0.03}{1})^{20}\\\\A=400(1+{0.03})^{20}\\\\A=400({1.03})^{20}\\\\A=400({1.8061})\\\\A=722.44 < ==round\ to\ the\ nearest\ dollar\\\\A=\$722

Note that since we are rounding, answers may vary by a dollar or two.

Hope this helps!

Dylan paid a plumber $120 for 4 hours of labor. How much does the plumber charge per hour of labor?
Lady bird [3.3K]
All you have to do is divide the 120 by 4 because you will be splitting it up into a individual hour. So 120 divided by 4 = 30.
The plumber charges $30/hour.

What are two fractions equal to 2/5?
Georgia [21]
Two fractions that are equal to 2/5 are 4/10 and 6/15. In order to find fractions that are equal to it, just multiply both the numerator and the denominator by any number. I multiplied them by 2 and 3, to keep things simple.

2 x 2 = 4
2 x 5 = 10
4/10

2 x 3 = 6
5 x 3 = 15
6/15

Hope this helps!
