Johnathan and Darius both tutor students part time on the weekends to earn extra money. Johnathan starts tutoring at 9:00am and earns $80.00 for every 3 hours he tutors. Darius starts at 10:30am and earns $30.00 every hour he tutors. If they keep on tutoring until Darius has earned the same amount of money as Johnathan, how much will they each earn?

If Darius earned $25.00 for every hour he tutored instead of $20.00 per hour, how would that change the answer to question 3?

I'll give brainliest if you answer right : )

The edge of a cube was found to be 30 cm with a possible error in measurement of 0.4 cm. use differentials to estimate the maximum possible error, relative error, and percentage error in computing the volume of the cube and the surface area of the cube. (round your answers to four decimal places.) (a) the volume of the cube maximum possible error cm3 relative error percentage error % (b) the surface area of the cube maximum possible error cm2 relative error percentage error %
