A 13 pound bag should cost $3.25.
Firstly, we divide $5.98 by 24lb to see how much each pound costs. (If we were to see this as a fraction, think of the numerator as the thing you’re trying to find, and the denominator as the thing you’re trying to “get rid” of.)
5.98 / 24 = $0.25. We can make it into an equation: y = 0.25x
X = amount of lbs, Y = the total cost.
since we are trying to find how much a 13lb bag costs, we put 13 as the x-value.
y = 0.25(13). y = 3.25.
