Question

Carly has already written 35 pages of a novel. She plans to write 12 additional pages per month until she is finished. Write and solve a linear equation to find the total number of pages written at 5 months.

Answer 1

f(x) = 12x+35

f(5) = 95 pages written at 5 months

Explanation:

Step 1: write the slope intercept equation

f(x) = mx+b

f(x) = the value of the equation at month x

m = slope of the linear equation (pages written PER month)

x = the month

b = intercept of the equation (pages already written)

Step 2: relate given information to the variables

m = 12 pages per month

b = 35 pages already written

Step 3: update equation

f(x) = 12x+35

Step 4: solve for x = 5 months

f(5) = 12(5) + 35 = 60 + 35 = 95
