Part A) Start at 0 on the number line. Count out 7 spaces (each space is 0.25 units wide) so you'll end up at 1.75 which is the total cost. The 7 spaces refer to the number of postcards purchased.

Part B) Multiply 0.25 by 7 and you should get 1.75; alternatively, you can multiply 25 by 7 to get 175, then move the decimal point 2 spots to the left to get 175 ---> 1.75

if you are saying purchasing 3 social media ads and one newspaper ad counts as one purchase then there are:

6 purchases

if you are asking how many of each then:

18 social media ads

6 newspaper ads

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
