Question

1. chris purchased the following items: • 2 binders at $4.99 each • 1 math set for $3.99 • a backpack for $19.99 find the total cost including 5% gst and 7% pst.

Explanation:

Step1: Calculate cost of binders

$\$4.99 \times 2 = \$9.98$

Step2: Sum pre-tax item costs

$\$9.98 + \$3.99 + \$19.99 = \$33.96$

Step3: Calculate total tax rate

$5\% + 7\% = 12\% = 0.12$

Step4: Compute total tax amount

$\$33.96 \times 0.12 = \$4.0752$

Step5: Find total cost with taxes

$\$33.96 + \$4.0752 = \$38.0352$

Answer:

$\$38.04$ (rounded to the nearest cent)
