So, a pizza place sells on average 55 pizzas a day.
That would mean that they sell 385 pizzas in a week. (55 x 7 = 385)
Monday is the worst day of sales, whereas Friday would be the best.
Friday sells 40% more (1.4x) than Monday.

The first step would be to find Monday.
Since Wednesday is in-between Monday and Friday, Wednesday would be considered as the "average" day and they would sell 55 pizzas that day.
That being said,
Monday has to be lower than Wednesday and Friday has to be higher than Wednesday.

What is the amount of pizzas that sells on Monday and Friday?
