Explanation:

Problem 5

Step1: Understand the increase

If this year's snow is 40% more than last year, we take last year's amount as 100%.

Step2: Calculate this year's percentage

To find this year's percentage of last year's amount, we add the 40% increase to 100%. So, \( 100\% + 40\% = 140\% \).

Step1: Understand the decrease

If this year has 25% fewer sunny days than last year, we take last year's number as 100%.

Step2: Calculate this year's percentage

To find this year's percentage of last year's number, we subtract the 25% decrease from 100%. So, \( 100\% - 25\% = 75\% \).

Step1: Understand the markup

A 93% markup means we add 93% of the ingredient price to the ingredient price.

Step2: Calculate the menu price percentage

To find the menu price as a percentage of the ingredient price, we add the 93% markup to 100% (the ingredient price itself). So, \( 100\% + 93\% = 193\% \).

Answer:

140
