Answer: 300 square feet  

Step-by-step explanation:

width of walkway = 15 + 2x

A(x) = (20 + 2x)(15 + 2x)

A(x) = 300 + 30x + 40x + 4x2

A(x) = 300 + 70x + 4x2

4. Tom decided to join Platinum Gym because of its new equipment. At the grand opening, the manager announced that 124 people ha
JulsSmile [24]

Number of people who signed up on the opening = 124

Number of people for whom registration fee is waived off = 50

Registration fee =  $60

Monthly fee = $20

Part A: Money it will make from the grand opening memberships = ?

⇒ Money it will make from the grand opening memberships = Money made from registration fee + Money made from first month's fee

⇒ Money it will make from the grand opening memberships = (Number of people who were charged registration fee ×  Registration fee per person) + (Number of people who registered × Monthly fee per person)

⇒ Money it will make from the grand opening memberships = (124 - 50) × 60 + (124 × 20)

⇒ Money it will make from the grand opening memberships = (74 × 60) + (124 × 20)

⇒ Money it will make from the grand opening memberships = (4,440) + (2,480)

⇒ Money it will make from the grand opening memberships = $6,920

Part B: Money made in 6 months, from the original 124 people who joined at the grand opening = ?

⇒ Money made in 6 months = Money made from registration fee + Money made from 6-months monthly fee

⇒ Money made in 6 months = (Number of people who were charged registration fee ×  Registration fee per person) + (Number of people who registered × Monthly fee per person × 6)

⇒ Money it will make from the grand opening memberships = (124 - 50) × 60 + (124 × 20 × 6)

⇒ Money it will make from the grand opening memberships = (74 × 60) + (124 × 20 × 6)

⇒ Money it will make from the grand opening memberships = 4,440 + 14,880

⇒ Money it will make from the grand opening memberships = $19,320

Hence, by the end of 6 months, the gym would have made $19,320
