☐ g + 0.05
☐ g + 0.05g
☐ 1.05g
☐ 0.05g
☐ (1 + 0.05)g

Explanation:

Step1: Calculate 5% increase amount

5% of \(g\) is \(0.05g\)

Step2: Find this week's price

This week's price = Last week's price + Increase = \(g + 0.05g\)

Step3: Simplify the expression

\(g + 0.05g = 1.05g\)

Step4: Check valid expressions

Valid expressions are \(g + 0.05g\) and \(1.05g\)

Answer:

B. \(g + 0.05g\), C. \(1.05g\)
