Question
Algorithms and data examples to be written:
Problem 1: (Hint: Use a sequential structure)
How do you calculate the miles you are getting per gallon of gasoline if you record the mileage readings
from your car's odometer each time you fill up the gas tank? Two odometer readings should be
inputted, one reading is before you fill up the gas tank, and the second reading is when you refill the gas
tank. The third input is the quantity of gallons of gasoline purchased when the gas tank is refilled. After
inputting these 3 values, calculate and output:
The miles traveled between gas refills
The average miles per gallon based on the miles traveled and the amount of gasoline purchased
after the time the gas tank is refilled

Problem 2: (Hint: Use a sequential structure)
How do you calculate the price you would pay for an item if it is on sale and you have an additional
discount coupon? To calculate the final price paid, 3 inputs are needed: the original price of the item,
the percent off because the item is on sale, and the discount percent of the discount coupon. Determine
and output all of the following:
The amount deducted from the original price of the item due to the item being on sale
The price of the item after the sales percent discount is subtracted
The amount of additional discount based on the discount coupon
The final price paid after the discount from the coupon is subtracted from the sale price
