Question

Mandy earns $10 a hour for tutoring. She has saved $20 dollars in her bank account. Write a equation for the total amount Mandy will have in her bank account, y, after x hours

Answer 1

how much does she have after zero hours? As in, how much does she have before she starts tutoring? This is at time, x, equal 0 hours.

Answer 2

she starts with $20, and she increases $10 for every hour she works.

so for x = 0 hours worked, she has y = $20

for x = 1 hour worked, she has y = $20 + $10(1)... the initial $20 + $10 for the hour worked.

for any x hours worked, the amount she has will be y = 20 + 10x

Answer 3

Good talk....
