1: A gratuity (also called a tip) is a sum of money customarily given by a client or customer to a service worker in addition to the basic price. It is common for certain countries especially in the West. You are asked to make a MATLAB' s program to calculate the tip based on amount of bills, using the following rules;
• bill less than $10, tip is $ 1.80

• bill is between $10 and $60, tip is 18%

• bill is above $60, tip is 20%

a) Draw a flowchart for the problem.
b) Write the MATLAB 's code for the problem that will also ask the user for the input and fmally will display the tip's amount.

2: Write a MATLAB' s code for converting centimeter unit (input x) to different units including inch, feet, meter, and wilindcx, You must use switch-case commands.

3: Write a MATLAB 's program that will use a while loop to find the smallest number divisible by both 3 and 5, with the square of the number greater than 33254
