You can divide 7.00 b y .21
7 ÷ .21 = 33.3333333
So you can buy 33 pencils for $7.00
Hope this helps you. :-)
n*(21/100)=(700/100)
n=(700/100)/(21/100)
n=(700/100)*(100/21)
n=700/21
n=33+1/3
So thirty three $0.21 pencils can be purchased for $7.00.
You can purchase thirty-three $0.21 pencils for $7.00. This is calculated by converting the amounts to cents and dividing the total cents by the cost of one pencil. After performing the calculation, you get 33 whole pencils.
