An algebraic expression for the cost of f cases of fruit will be (a) z = 13f and the cost for 250 cases will be (b) $3250.
Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the cost of the fruit is z
Given,
The marching band is selling cases of fruit for $13 per case.
So for f cases of fruit
z = 13f
And cost of 250 cases = z = 13(150) = $3250
Hence, the algebraic expression for the cost of f cases of fruit will be z = 13f and the cost for 250 cases will be $3250.
