Explanation:

Step1: Identify taxed items

In Canada, cell - phones, take - out, and chips are generally taxable at the 13% HST rate. Diapers, kids' clothes, and prescriptions are often tax - exempt. So the items to circle are Cell phones, Take Out, Chips.

Step2: Calculate tax and total for table items

For an item with price $P$, tax $T = 0.13P$ and total $C=P + T=P(1 + 0.13)=1.13P$.

Item 1:

$P_1=\$17.99$
$T_1=0.13\times17.99=\$2.3387\approx\$2.34$
$C_1=17.99 + 2.34=\$20.33$

Item 2:

$P_2=\$246.97$
$T_2=0.13\times246.97=\$32.1061\approx\$32.11$
$C_2=246.97+32.11=\$279.08$

Item 3:

$P_3=\$1.27$
$T_3=0.13\times1.27=\$0.1651\approx\$0.17$
$C_3=1.27 + 0.17=\$1.44$

Step3: Calculate for first receipt

Subtotal $S_1=4.99 + 13.99=\$18.98$
Tax $T_{r1}=0.13\times18.98=\$2.4674\approx\$2.47$
Total $C_{r1}=18.98+2.47=\$21.45$

Step4: Calculate for second receipt

Subtotal $S_2=1.75+2.00 + 1.50+1.50+1.75+2.00=\$10.50$
Tax $T_{r2}=0.13\times10.50=\$1.365\approx\$1.37$
Total $C_{r2}=10.50 + 1.37=\$11.87$
