Samantha has $300 for guitar lessons to learn her favorite song mr. Jones charges $800 per lesson and requires three lessons to
teach Samantha and the song. Mr police charges $62 per lesson and and will require four lessons to teach Samantha the song. Use integers to represent which teacher each charges. Which is better deal for Samantha
Just multiply the 0.003 by 10 and you'll get the result. The easiest way to multiply such numbers is to move the dot one position to the right (it would be 2 positions if multiplying by 100, 3 by 1000 etc.). You can do the same with dividing, just remember to move to the left then.
