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

Cost of 2 binders: \(2\times4.99 = 9.98\)

Step2: Sum all item costs

Total before tax: \(9.98 + 3.99 + 19.99 = 33.96\)

Step3: Calculate total tax rate

Total tax rate: \(5\% + 7\% = 12\% = 0.12\)

Step4: Calculate tax amount

Tax amount: \(33.96\times0.12 = 4.0752\)

Step5: Calculate total cost

Total cost: \(33.96 + 4.0752 = 38.0352\approx38.04\)

Answer:

The total cost including taxes is approximately \(\$38.04\)
