Kyle bought himself a pair of shoes for 89.50 and he bought his nephew a pair for half the price of his shoes. If the sales tax

ycow [4]

Solution-

89.50/2 = 44.75

44.75 is the amount he spent to buy his nephew the pair of shoes.

Now, we are going to add the amount he spent for himself and his nephew together.

89.50 + 44.75= 134.25

134.25 is the amount he spent in total, now we need to find the final amount with sales tax included.

We can do this by multiplying the total price by .075

134.25 * .075 = 10.07 (I rounded this to the nearest hundredths because we are dealing with money)

Now we need to add the two number together.

134.25 + 10.07 = 144.32

Answer-

The total amount Kyle spent is $144.32

Last year, Keiko had $20,000 to invest. She invested some of it in an account that paid %7 simple interest per year, and she inv

erma4kov [3.2K]

Answer:

$P_2 = \$6,000\\P_1 = \$14,000$

Step-by-step explanation:

The formula of simple interest is:

$I = P_0rt$

Where I is the interest earned after t years

r is the interest rate

$P_0$ is the initial amount

We know that the investment was $20,000 in two accounts

_______________________________________________

<u><em>For the first account</em></u> r = 0.07 per year.

Then the formula is:

$I_1 = P_1r_1t$

Where

$P_1$ is the initial amount in account 1 at a rate $r_1$ during t = 1 year

$I_1 = P_1(0.07)(1)\\\\I_1 = 0.07P_1$

<u><em>For the second account </em></u>r = 0.05 per year.

Then the formula is:

$I_2 = P_2r_2t$

Where

$P_2$ is the initial amount in account 2 at a rate $r_2$ during t = 1 year

Then

$I_2 = P_2(0.05)(1)\\\\I_2 = 0.05P_2$

We know that the final profit was I $1,280.

So

$I = I_1 + I_2=1,280$

Substituting the values $I_1$ , $I_2$ and I we have:

$1,280 = 0.07P_1 + 0.05P_2$

As the total amount that was invested was $20,000 then

$P_0 = P_1 + P_2 = 20,000$

Then we multiply the second equation by -0.07 and add it to the first equation:

$0.07P_1 + 0.05P_2 = 1.280\\.\ \ \ \ \ \ \ \ +\\-0.07P_1 -0.07P_2 = -1400\\-------------$

$-0.02P_2 = -120\\\\P_2 = 6,000$

Then $P_1 = 14,000$

What Is the slope of the line that passes through these two points (-5,7) and (6,4)

Snowcat [4.5K]

Answer:

slope = - $\frac{3}{11}$

Step-by-step explanation:

Calculate the slope m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 5, 7) and (x₂, y₂ ) = (6, 4)

m = $\frac{4-7}{6+5}$ = $\frac{-3}{11}$ = - $\frac{3}{11}$
