Question

Samuel needs 233 feet of wood to build a fence. The wood comes in lengths of 11 feet. How many total pieces of wood will Samuel need?

Answer 1

Divide 233 by 11. The quotient is 21.1818181818 repeating. Because you can't have a fraction of a piece of wood, Samuel will need 22 pieces of wood in all. I hope this helps!

Answer 2

For this case, the first thing we must do is define variables:

x: total amount of wood feet

y: measure of each piece of wood in feet

n: total number of pieces of wood

We now write the equation that models the problem:
