Mr. Gonzalez earns his living as a salary plus commission employee. His annual salary is $18,000. He makes 4% commission on all of his sales. Mr. Gonzalez wants to earn $60,000 this year. If his earnings are divided evenly throughout the year, how much in monthly sales would Mr. Gonzalez need to have?

Answers

Mr. Gonzalez's monthly sales must be $87,500.

What is percentage?

"It is a number or ratio that can be expressed as a fraction of 100"

For given example,

Let 's' represents the monthly sale.

So, the annual sales are 12 × s

He makes 4% commission on all of his sales.

So, the commission on (12 × s) sales would be,

= 12 × s × (4%)

= 12× s × 0.04

Mr. Gonzalez wants to earn $60,000 this year.

So, we get an equation,

⇒ 18000 + (12 × s × 0.04) = 60000

⇒ 12 × s × 0.04 = 60000 - 18000

⇒ 12 × s × 0.04 = 42000

⇒ s × 0.04 = 42000/12

⇒ s × 0.04 = 3500

⇒ s = 3500/0.04

s = 87500

Therefore, Mr. Gonzalez's monthly sales must be $87500.

I'VE ASKED THIS ONE EARLIER BUT NOBODY ANSWERED Point D is in the interior of \small \angle ABC, \small m\angle ABC=20x-15, \small m\angle ABD=6x-5, and \small m\angle DBC=x+16. What is \small m\angle ABD? \small m\angle ABD= degrees

Answers

Answer:

Step-by-step explanation:

Since, Point D is in the interior of angle ABC.

Therefore,

[tex]m\angle ABC = m\angle ABD + m\angle DBC\\

20x - 15 = 6x - 5 + x + 16\\

20x - 15 = 7x + 11\\

20x - 7x = 11+15\\

13x = 26 \\ x = \frac{26}{13} \\ x = 2 \\ \\ m\angle ABD = (6x - 5) \degree \\ m\angle ABD = (6 \times 2 - 5) \degree\\ m\angle ABD = (12 - 5) \degree \\ \huge \red{ \boxed{ m\angle ABD = 7\degree}}[/tex]

Solve for the given variable 7x+5y=6 for y

Answers

Answer:

y = (6/5) - (7/5) x

Step-by-step explanation:

goal: to rearrange the equation such that it takes the form:

y = f(x) ; where f(x) is an expression in terms of x

Given:

7x+5y=6   subtract 7x from both sides

5y = 6 - 7x   (divide both sides by 5)

y = (6-7x) / 5

y = (6/5) - (7/5) x

Answers

Answer:

840

Step-by-step explanation:

There is a common difference d between consecutive terms, that is

d = 14 - 7 = 21 - 14 = 7

This indicates the sequence is arithmetic with n th term

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = 7 and d = 7 , thus

[tex]a_{120}[/tex] = 7 + (119 × 7 ) = 7 + 833 = 840
