Answer: $43.50
Explanation:
In the problem we are given the cost of two scarves, which is $29. However, we are not informed of the cost of each individual scarf which is the first step we must take in finding the cost of three. The easiest way to do this is to set up an equation.
Let the variable x=the cost of one scarf
2x=29
Using previous knowledge of problem solving and inverse operations, we know that in order to get the x by itself, we must divide by two to cancel out the multiplication by two.
2x=29
2 2
x = 14.5
Now that we have the cost of one scarf, we can plug in that amount to get the cost of three
3(14.5)= 43.5
