Answer: import math
# Step 1: Read input values and calculate wall area
wall_height = float(input())
wall_width = float(input())
paint_cost = float(input())
wall_area = wall_height * wall_width
print(f"Wall area: {wall_area:.1f} sq ft")
# Step 2: Calculate amount of paint needed
paint_needed = wall_area / 350
print(f"Paint needed: {paint_needed:.3f} gallons")
# Step 3: Calculate number of cans needed
cans_needed = math.ceil(paint_needed)
print(f"Cans needed: {cans_needed} can(s)")
# Step 4: Calculate and output costs
paint_cost_total = paint_cost * cans_needed
sales_tax = 0.07 * paint_cost_total
total_cost = paint_cost_total + sales_tax
print(f"Paint cost: ${paint_cost_total:.2f}")
print(f"Sales tax: ${sales_tax:.2f}")
print(f"Total cost: ${total_cost:.2f}")
Step-by-step explanation:
The input() function is used to read the wall height, wall width, and cost of one paint can as floats.
The wall area is calculated by multiplying the wall height and width, and then printed using formatted string literals to one decimal place.
The amount of paint needed is calculated by dividing the wall area by 350, the amount of square feet that one gallon of paint can cover. The result is printed to three decimal places.
The number of cans needed is calculated using the math.ceil() function to round up the value of paint_needed to the nearest integer.
The total cost of the paint is calculated by multiplying the cost of one paint can by the number of cans needed. The sales tax is calculated as 7% of the paint cost total. The total cost is calculated by adding the paint cost total and sales tax. All of these values are printed using formatted string literals to two decimal places.
Note: It's important to ensure that the input values are entered correctly, including the decimal points.
