Answer:

10 miles to earn 200 cash

Steps:

80 + 12m = 200

12m = 200 - 80

12m = 120

12m/12 = 120/12

m = 10

Answer:

200 = 80+12m

10 miles

Step-by-step explanation:

She will get 80 from the first and 12m from the second

She needs 200

200 = 80+12m

Subtract 80 from each side

200 -80 = 12m

120 = 12m

Divide each side by 12

120/12 = m

10 =m

She needs to walk 10 miles
