The SHS step team is selling shs spirit t-shirts to raise money. The orange/black shirt sells for $15 and the black/white shirt

IRINA_888 [86]

Answer:

Option A)

$15x + 10y \geq 1000$

Step-by-step explanation:

We are given the following in the question:

Cost of orange/black shirt = $15

Cost of black/white shirt = $10

Amount of money to be raised is atleast $1000.

Let x be the amount of orange/black shirt and y be the amount of black/white shirt.

Thus, we can write the inequality:

$15x + 10y \geq 1000$

That is the total cost of orange/black shirt and black/white shirt should be greater than or equal to $1000.

Thus, the correct answer is

Option A)

$15x + 10y \geq 1000$

Anisha invested $8,000 in an account that earns 10% interest How much money will she have in 15 years of the interest is compoun

tamaranim1 [39]

Answer:

A = $35,198.32

Step-by-step explanation:

Use the formula to calculate compound interest:

A = P(1 + i)ⁿ

"A" for total amount after the time period

"P" for principal, or starting money

"i" for the interest rate in a compounding period

To calculate "i":

i = r / c

"n" for the number of compounding periods

To calculate "n":

n = tc

So, we can combine the formulas into:

$A = P(1+\frac{r}{c})^{tc}$

"c" is the compounding periods in a year. (quarterly = 4)

We know:

P = 8000

r = 10% / 100 = 0.1

t = 15

c = 4

Substitute the information in the formula.

$A = P(1+\frac{r}{c})^{tc}$

$A = 8000(1+\frac{0.1}{4})^{15*4}$ Solve "i" and "n"

$A = 8000(1+0.025)^{60}$ Solve inside the brackets

$A = 8000(1.025)^{60}$ Do the exponent before multiplying by 8000

A = 35198.318 Exact answer

A ≈ 35198.32 Round to two decimal places for money

Therefore she will have $35,198.32 after 15 years.

Tju [1.3M]

Answer: 10

Step-by-step explanation:

$(\frac{1}{2}+\frac{3}{4})$ ÷ $\frac{1}{8}$

= $(\frac{1}{2}(\frac{2}{2})+\frac{3}{4})$ ÷ $\frac{1}{8}$

= $(\frac{2}{4}+\frac{3}{4})$ ÷ $\frac{1}{8}$

= $(\frac{5}{4})$ ÷ $\frac{1}{8}$

= $(\frac{5}{4})$ x $\frac{8}{1}$

= $\frac{40}{4}$

= 10
