Daniel is planning a 6-night road trip. it will cost $310 for transportation, $275 for food, and $70 per night for a hotel room. he has $745 in savings and can earn $20 per hour tutoring. how many hours must he tutor to have enough money to pay for the trip?

Daniel must tutor 160 hours

Explanation:

310+275+70= 655

655×6= 3930 (he needs this amount of $)

(Daniel gains $20 per hour)

20×160= 3200

3200+745= 3945

3945 > 3930

Daniel has enough for the trip.

Where did I get 160?

Well, I was just trying out numbers and multiplying it by 20

The numbers I tried: 100, 150, 156, 159 & 160 but only 160 fit with the answer.

If it was just one night road trip he would've just needed $655, but since it's a 6-night road trip I multiplied it by 6.

Hope this helped!

the number 100 represents the number of trials in the experiment.

49/100 represents the experimental probability of the coin landing heads up.
