Gina and rhonda work for different real estate agencies . gina earns a monthly salary of 5,000 plus 6% commission on her sales . rhonda earns a monthly salary of 6,500 plus a 4% commission on her sales . how much must each sell to earn the same amount in a month

$325000

Step-by-step explanation:

In order to solve this, you need to create an equation, we know that they earn 5,000 and 6,500 each plus comissions the comissions will be represented by "x" and then you just have to equalize both terms:

And now we just solve for x:

They both have to sell $325,000 so in comissions their wages will equalize.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
