B, 12% 18% 26% 44%

Step-by-step explanation:

So if each of these were answered out of a subject pool of 50 students, they can all become fractions.

22/50

6/50

13/50

9/50

Percentages are about the decimal though. To get a decimal from a fraction, divide the numerator by the denominator.

22÷50=0.44

6÷50=0.12

13÷50=0.26

9÷50= 0.18

Take the decimal place and carry it to the right, like you would to the hundredths place. These new numbers are your percentages.

44% 12% 26% 18%

a) t'(-3, 6) and v'(0, 3)  

step-by-step explanation:

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
