<h3>Answer:</h3>

y = 0.1x +1500

<h3>Explanation:</h3>

You need an equation that will give Gary a salary of $1500 even if he makes no sales (x=0). The only possible choice for the second item is then ...

... +1500

You are expected to know that Gary's commission of 10% of sales is computed by multiplying sales (x) by 10%. That is, if Gary sells $100 worth of items, his commission is ...

... 10% × $100 = $10

That is, the multiplier is 0.1.

Gary's salary (y) is then computed as

... y = 0.1x +1500

_____

<em>Comment on percentages</em>

The % symbol is a shorthand way to write /100. That is, 10% = 10/100, ten hundredths, or 0.10. (You might notice here that "percent" and "hundredths" can be used interchangeably.)

SOlve the equation <br><br> 0.25 r - 0.125 + 0.5 r = 0.5 +r
seropon [69]
You put all the numbers on one side of the equation and letters on another. 

0.25r + 0.5r - r = 0.5 +0.125 

-0.75r  = 0.625    divide both sides by -0.75

r = -0.125

Iago is interested in money. He has a collection of bills in his pocket. He finds that he has two fewer $20 bills than he does $
Colt1911 [192]

Let x be the number of $10 bills in Iago pocket.

1. If he has twice as many $1 bills as $10 bills, then he has (2x) $1 bills.

2. He has two fewer $20 bills than he does $10 bills, then he has (x-2) $20 bills.

3. He has three more $5 bills than $10 bills, then he has (x+3) $5 bills.

In total he has $160 that is x·10+2x·1+(x-2)·20+(x+3)·5.

Equate these two expressions and solve the equation:

x\cdot 10+2x\cdot 1+(x-2)\cdot 20+(x+3)\cdot 5=160,\\ \\10x+2x+20x-40+5x+15=160,\\ \\37x=160+25,\\ \\37x=185,\\ \\x=5.

Thus, he has

  • 5 bills for $10;
  • 10 bills for $1;
  • 3 bills for $20;
  • 8 bills for $5.
