Answer 1

a. An expression in the simplest form that represents the difference between the number of subscriptions your friend has sold and the number you have sold is (w + 3).

b. After 4 weeks, your friend has sold 7 more subscriptions than you.

An expression is a combination of numbers, constants, or values and variables, but without the use of the equals sign (=).

a) The number of subscriptions sold by you after W weeks = (8w + 2)

The number of subscriptions sold by your friend after W weeks = (9w + 5)

The difference between the number of subscriptions sold by your friend and you = (9w + 5) - (8w + 2) = (w + 3)

b) The number sold by your friend after 4 weeks = (9(4) + 5) = 41

The number sold by you after 4 weeks = (8(4) + 2) = 34

Difference between the number of subscriptions sold = 7 (41 - 34)
