Aclub is making posters to raise money. the printer charges a base fee of $270 and $2 per poster for supplies. a person sells each poster for $ 5. how many posters must he sell to make a profit of $ 300?

He must sell 190 posters make a profit of $300.

Explanation:

Given:

Base fee= $270  

Fee for supplies= $2

Cost of poster=$5

To find:

The number of posters to be sold to get a profit of $300=?

Solution:

Let the number of posters sold be n.

Now, we know that,

profit = selling price – cost price

$ 300 = $ 5 for each poster – ( $ 270 base fee + $ 2 for each poster)

300 = 5 x n – (270 + 2 x n)  

300 = 5n – 270 – 2n  

5n – 2n = 300 + 270  

3n = 570  

n = 190

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.
