4 pencils cost 10 cents so pencils are 10/4 cents each.
So 50 cents will buy 50*4/10 = 20 pencils
To determine how many 21-cent pencils can be bought with 7 dollars, you first need to find out how many cents are in 7 dollars. Since there are 100 cents in a dollar, 7 dollars is equal to 700 cents. To find out how many pencils can be bought, divide the total amount of cents (700) by the cost of each pencil (21 cents). This calculation results in approximately 33 pencils that can be bought with 7 dollars.
If two lemons cost 15 cents, then one lemon costs 7.5 cents. To find out how many lemons can be bought for 60 cents, divide 60 by 7.5, which equals 8. Therefore, you can buy 8 lemons for 60 cents.
3x12x2=72
To find out how many pencils can be bought with $4.00 when each pencil costs $0.25, divide the total amount of money by the cost of one pencil. This is calculated as follows: $4.00 ÷ $0.25 = 16. Therefore, you can buy 16 pencils with $4.00.

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
Eighteen pencils !
Oh, dude, if you bought 3 gross of pencils, you would have 432 pencils. Yeah, that's right, a gross is 144 pencils, so just multiply 144 by 3 and boom, you've got yourself a whole lot of pencils. Like, who even needs that many pencils, am I right?
I'll represent the cost of a pencil by the variable p.12p=1.44p=1.44/12p=0.12So 4 pencils would cost:4p=0.12*44p=0.48
