Astudent charges twenty dollars per hour to type college papers. the student's average typing speed is fifty words per minute. at this rate, how much should the student charge for typing a paper that contains 31,500 words? a) $175 b) $195 c) $210 d) $230

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

ok then what happened.

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.
