Explanation:

Problem 1:

Step1: Convert cost to dollars

Material cost = 35 cents = $\$0.35$

Step2: Calculate profit (Selling Price - Cost)

Profit = $1.50 - 0.35 = \$1.15$

Step1: Calculate profit (Revenue - Cost)

Profit = $130 - 55 = \$75$

Step2: Calculate ROI (Profit / Cost * 100%)

ROI = $\frac{75}{55} \times 100\% \approx 136.36\%$

Step1: Calculate profit (Selling Price - Cost)

Profit = $180 - 30 = \$150$

Step2: Calculate ROI (Profit / Cost * 100%)

ROI = $\frac{150}{30} \times 100\% = 500\%$

Answer:

$\$1.15$
