Question

Lisa is saving $50 that she received from her grandmother. She earns $6 each time she walks her neighbor's dog, which she also saves. Which function can be used to find f, the amount of money Lisa will have saved after walking the neighbor's dog d times?

Answer 1

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
