Economy printing

Our printer is often used by students, and saving money is very important for them. Saving on everything. Our analysts found out that teachers usually read no more than the first three pages of all reports, course books and other student documents. From this secret knowledge, the idea of a printing mode for students was born: the first three pages are printed as usual, and then we save as much as we can on all the remaining pages (that is, we use two times less toner)!

Now we don’t just need to increase the value of consumptionTotal for each iteration by 70, but we also need to check which print mode we are using (economy or standard) and which page of the document (number) we are printing. Conditions will be useful here.

Use the condition in the loop to check the print mode. If we are in economy mode, we will catch pages with a number greater than 3 and print them with lower ink consumption. We will write half of the consumption as consumptionPerPage * 0.5.

script.js

JavaScript

var totalPages = 6; // Total number of pages var consumptionTotal = 0; // Total toner consumption var consumptionPerPage = 70; // Toner consumption per page for (var page = 1; page <= totalPages; page++) { muffin.print(page); // Add the check here consumptionTotal += consumptionPerPage; console.log(consumptionTotal); }

After the consumptionPerPage variable, create variable economyMode, which contains false.
In the loop after calling muffin.print(), add a condition that works if economyMode equals true and if the number of the current page page is greater than 3.
Inside this condition, increase consumptionTotal by consumptionPerPage * 0.5 with the help of the += operator.
