Answer:

0.2w^2+4w+3

Step-by-step explanation:

a(w)=−0.4w^2+5w+9

c(w)=−0.2w^2+9w+12

We want to find the how many more children than adults

f(w) = c(w) - a(w)

    = −0.2w^2+9w+12 - ( −0.4w^2+5w+9)

Distribute the minus sign

= −0.2w^2+9w+12 +0.4w^2-5w-9

Combine like terms

 = 0.2w^2+4w+3

Uber is now charging a $2.50 flat rate in addition to $0.75 per mile for your ride. Janae can spend at most $13 on her Uber Ride
Alex777 [14]

Answer:

  • B: 10

Step-by-step explanation:

<u>Full charge can be expressed as equation:</u>

  • c = 2.5 + 0.75m, where c- charge, m- miles

<u>The limit for charge is $13, then we got inequality:</u>

  • 0.75m + 2.5 ≤ 13
  • 0.75m ≤ 9.5
  • m ≤ 9.5/0.75
  • m ≤ 12.66

Option B: 10 is correct as the only number satisfying the inequality
