Plz help me with all of this question here and explain how was the incorrect answer obtained
larisa [96]

Answer:

1.) 9

2.) 20

Step-by-step explanation:

1.) 39 is incorrect because they didn't follow the PEMDAS rule.

They subtracted 2 from 15 which is 13, and then they multiplied 13 by 3.

<u>The correct way is to multiply 2 times 3 which is 6, and then subtract 6 from 15 which is 9.</u>

<u />

2.) 12 is incorrect because they didn't use PEMDAS.

They added 8 to 16 which is 24, and then divided 24 by 2.

<u>The correct way is to divide 8 by 2 which is 4, and then add for to 16 which 20.</u>

Lina20 [59]

Answer:

Caroline has to pay $8600 taxes

Jennifer has to pay $10320 taxes

Step-by-step explanation:

I guess the question is who has to pay how much taxes, right ?

Caroline earns $49000, and I guess, she belongs to a health fund.

she has to pay $5000 for the first $40000.

and for the remaining $9000 she has to pay $0.40 per dollar.

that means 9000×0.4 = $3600

and no penalties for no health fund.

so altogether $5000 + $3600 = $8600 taxes

Jennifer earns $51000 and did not belong to a health fund.

she has to pay $9000 for the first $50000.

and for the remaining $1000 she had to pay $0.30 part dollar.

that means 1000×0.3 = $300

and 2% of the total income because no health fund

51000×0.02 = $1020

so, altogether $9000+$300+$1020 = $10320 taxes
