Answer:

3. $600,000

Step-by-step explanation:

We have been given that a tenant rented a store to use as a real estate school at a base rent of $1,500 a month. Additionally, the tenant agreed to pay 3% of gross annual sales over $200,000.

Let us find base annual rent.

$\text{Base annual rent}=\$1500\times 12\\\\ \text{Base annual rent}=\$18,000$

Let us find the amount of rent paid as 3% of gross annual sales.

$\$30,000-\$18,000=\$12,000$

Let us find amount of sales over $200,000 by dividing $12000 by 3% or 0.03.

$\frac{\$12,000}{0.03}=\$400,000$

Total sales would be $400,000 plus $200,000.

$\text{Total sales}=\$400,000+\$200,000\\\\ \text{Total sales}=\$600,000$

Therefore, the total sales for that year was $600,000 and 3rd option is the correct choice.

If dy/dx = y cos x and y = 3 when x = 0, then y =....? Here are the answer choices

creativ13 [48]

Dy/dx = y cos x
y = Ae^sin(x)
y(0) = Ae^sin(0) = A = 3
A = 3

Therefore, y = 3e^(sinx)

s2008m [1.1K]

Answer:

31.5 cm²

Step-by-step explanation:

Calculate area of a triangle with this formula:

Area = $\frac{1}{2}$ base * height

Substitute in known values

Area = $\frac{1}{2}$ 7 * 9

Multiply 7 by 1/2

Area = 3.5 * 9

Multiply

Area = 31.5 cm²

Hope this helps :)
