Answer:

y = 6.50x + 6

6.50x because it it per person

6 because it is a flat one time charge

We want the max to be 71 so that will be our y

71 = 6.50x + 6

We are now going to solve for x

65 = 6.5x

x = 10

A map using the scale of 3/4 of an inch to aubergine 3 miles if the actual distance between two cities is 25 miles then what is

mafiozo [28]

Answer:

6.25 inches

Step-by-step explanation:

3/4 inches = 0.75 inches

If 0.75 inches is the map's scale for 3 miles, then:

0.75 inches / 3 miles = 0.25 inches per 1 mile

Multiply 0.25 inches inches per mile * 25 miles:

0.25 * 25 = 6.25 inches

OR:

0.75/3 = x/25

Multiply 25 by both sides:

x = (0.75/3)*25

x = 6.25 inches
