inches, inches, inches, inches

The answer to your question is a) 2 in b) 3 in c) 4 in d) 6 in

Step-by-step explanation:

Data

scale 1 in = 40 mi

a) 80 mi

b) 120 mi

c) 160 mi

d) 240 mi

Process

To solve this problem use proportion and cross multiplication

a)

                       1 in 40 mi

                        x     80 mi

                        x = (80 x 1) / 40

                        x = 2 in

b)        

                       1 in 40 mi

                        x     120 mi

                        x = (120 x 1) / 40

                        x = 3 in

c)

                       1 in 40 mi

                        x     160 mi

                        x = (160 x 1) / 40

                        x = 4 in

d)

                       1 in 40 mi

                        x     240 mi

                        x = (240 x 1) / 40

                        x = 6 in

2nd one in the first row is correct

$30.32

step-by-step explanation:

65.00*.12=2.80

65.00-2.80=57.20

57.20*1.06=60.632

60.632/2=30.316
