Respuesta :

Let

f ------> the amount of money Lisa will have saved

d -----> number of times that she walking the neighbor's dog

so

Remember that

The linear equation in slope intercet form is equal to

f=md+b

where

m is the unit rate or slope

b is the y-intercept or initial value

in this problem we have

m=6

b=50

therefore

substitute

f=6d+50

answer is last one option
