14m - 7 - 35m = 260 - 195m
-21m + 195m = 260 + 7
174m = 267

Abdull sells computers for a local computer outlet. He gets paid $400 per month plus a commission of 4.2% on all the computer ha

Fed [463]

Ok. So… Let's see if I can solve this one.

So since they wanted 4.2% out of the 640,000 Abdull makes, we can move the decimal(4.2%) to the left twice. Which will get .042 . The afterword-that will allow us to multiply 640,000 dollar with .042 . Which mean Adbull has receive 26,880 cash that year.

Answer for “A” = 26,880

Ok so his annual salary plus his commission. That means his 400 dollar (per month) plus the amount on the sales commission. Which mean… 400 dollar(Monthly) plus 26,880 dollars. Which will get us 27,280

A = 26,880

B = 27,280

(Im not sure about answer B because Im not sure if they are talking about yearly price for both or monthly payment for 400 dollar plus the monthly commission.) But overall, their,you have your answer.

Ella collects 50 bottles to recycle. Of the bottles she collects, 19 are plastic and the rest are glass.

nekit [7.7K]

QUESTION A

The total number of bottles Ella collected is
$50$

The number of bottles that are plastic is

$19$

The percentage of bottles that are plastic is

$= \frac{number \: of \: plastic \: bottles}{total \: number \: of \: bottes} \times 100\%$

$= \frac{19}{50} \times 100\%$

$= 19 \times 2\%$
$= 38\%$

Therefore 38% of the bottles are plastic.

QUESTION B

The total number of bottles that are glass is
$50 - 19 = 31$

The total number of bottles Ella collected is
$50$

The percentage of bottles that is glass is
$= \frac{number \: of \: glass \: bottles}{total \: number \: of \: bottles} \times 100\%$

$= \frac{31}{50} \times 100\%$

$= 31 \times 2\%$
$= 62\%$

Therefore 62% of the bottles are glass
