Complete question :

Mary earned $35.00 for walking her neighbor's dogs. Mary charged a flat fee of $5.00 to walk the dogs. Mary also charged $2.50 for each hour she walked the dogs. For exactly how many hours did Mary walk her neighbor's dogs?

12 hours

Step-by-step explanation:

Given that:

Mary's charge rate :

Flat fee = $5

Amount charged per hour (hourly charge) = $2.50

Amount earned = $35

Hence,

Amount earned = flat fee + (hourly charge * number of hours)

Let number of hours = h

35 = 5 + 2.50h

35 - 5 = 2.50h

30 = 2.50h

h = 30/2.5

h = 12

Hence, Mary walked her neighbor's dog for 12 hours

step-by-step explanation:

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
