Question

Ethan has $20 saved and he earns $6.50 per hour. he wants to have at least $100 in his savings account.

write an inequality to represent how many hours ethan will need to work to save at least $100.

Answer 1

Alrighty lets work this out. Ethan has 20 dollars already so if we do the math we can subtract 100-20=80 so we know that Ethan needs to earn 80 more dollars to have 100 dollars in his savings account. We also know that Ethan earns $6.50 per hour so we can divide 80 from 6.50 which is 12.30, So he works 12 hours and 30 minutes more to earn one hundred dollars. I hope this helped!
