Since there are 2 semesters per year we have:
(1/2)(24,870 - 7,560) = $8,655
David would have to contribute $8,655 per semester.
a: 27.324 (rounded to the nearest cent is $27.32)
b: 18.0088% (rounded to the nearest percent is 18.01% or 18%)
The fractions in this equation are 3/4 and 5/6. The denominators of those fractions are 4 and 6. The lowest common multiple (LCM) of the numbers 4 and 6 is 12. The LCM is 12 because this is the smallest multiple 4 and 6 have in common
Multiples of 4 are: 4, 8, 12, 16, 20, 24, 28, 32, ....
Multiples of 6 are: 6, 12, 18, 24, 30, 36, 42, 48, ....
The LCM has been highlighted in bold to make it easier to spot
Therefore, the LCD (lowest common denominator) of the fractions is 12. If we were to multiply both sides of this equation by the LCD, then we will clear out the fractions entirely to have whole numbers only left over.
