Actually, the answer is "eight twenty-first-ths"
First, we need to restate the problem as thus: For every 70 cents, one can buy 72 pencils (equal to 6 dozen pencils). Thus, for every x cents, one can buy 3 pencils. In numerical form, this equation turns into $0.70/72 pencils = $x/3 pencils, or 0.70/72 = x/3. Simplified, one gets (3)(0.70) = 72x, or 2.1 = 72x. Hence, x=2.1/72=0.029, or $0.03, or 3 cents. So 3 pencils actually cost 3 cents. If one were to sell 3 pencils for 20 cents, one would have a profit of 17 cents for 3 pencils.
First we convert to the same type, which is twenty-fourths: 6 twenty-fourths + 9 twenty-fourths + 10 twenty-fourths = 25 twenty-fourths or 1 and 1 twenty-fourth.

There has never been any lead in lead pencils. The graphite deposit that produced the first pencils was mistakenly thought to be lead. Chemists pointed out the error but the name stuck.

Colored pencils were first developed and made around 1920 by the A.W. Faber company, located in Stein, Germany.
nope, twenty-first century is fine
x= # of pencils that cost .45 y= # of pencils that cost .65 So now you need 2 equations for 2 variables: 15= x+y This equation is saying: 15 total pencils bought= pencils that cost .45 + pencils that cost .65 The second equation is: 7.75= .45x + .65y This equation is saying: total money spent (7.75)= price of pencils (.45) times # of pencils + price of pencils (.65) times # of pencils Then you combine these two equations, but first switch around the first equation to look like: y=15-x Then you replace the "y" in the second equation by putting in what y equals the first equation: 7.75= .45x + .65(15-x) Then distribute and solve for x: x = 10 Then enter 10 into the first equation for x to figure out y: y= 15- 10 y= 5 So your answer is-- Ray bought 10 pencils that cost .45 and 5 pencils that cost .65
