Dalaysia is participating in a walk-a-thon. One sponsor will donate $80 just for entering the race. Another sponsor will donate $12 for each mile she walks. How many miles should she walk if she
wants to raise exactly $200 from those two sponsors? )
Let m represent the number of miles Dalaysia walks. Write an equation that
represents the number of miles Dalaysia needs to walk to raise exactly $200 from
the two sponsors. 1)

10 miles to earn 200 cash

Steps:

80 + 12m = 200

12m = 200 - 80

12m = 120

12m/12 = 120/12

m = 10

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
