Exercise 13 Page 273

Let the average price of one shirt be x. Then write the expression for the cost of 4 shirts.

Equation: 4x=52
Cost: $13

Practice makes perfect

Let's call the average cost of one shirt x. Since Nancy bought 4 shirts, she paid 4x for all of them. We are also given that she paid a total of $52 for these shirts. We can equate these expressions. 4x=52 Now we have an equation that we can solve for x.

4x=52

.LHS /4.=.RHS /4.

x=52/4

Calculate quotient

x=13

The average cost of one shirt is $13.
