3x12x2=72
4 pencils cost 10 cents so pencils are 10/4 cents each.So 50 cents will buy 50*4/10 = 20 pencils

45.30 ÷ 7.55 = 6
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.
Eight pencils.
There will be: (3*10)-25 = 5 pencils left over
3x12x2=72
If pencils cost 0.26 each could you buy four pencils with 1.00?
