Exercise 1 Page P3

It is given that Addison paid $\$1.29$ for gum and $\$0.89$ for the package of notebook paper. Adding these together will give us the total amount she paid for her goods. The tax for this purchase is $\$0.14.$ If we add this to the amount spent on goods, we get the total amount Addison paid. Since she gave a $\$5$ bill, we can calculate the amount of change by subtracting $\$2.32$ from $\$5.$ Addison should receive $\$2.68$ in change.
