More Inequalities

In class we did some more practice of shading inequality regions.  If you found this hard, look at this guide which explains the topic very clearly.

If you want to try a wordy question like the one we did in class, try this one:
The school hall seats a maximum audience of 200 people for performances. Tickets for the Christmas concert cost £2 or £3 each. The school needs to raise at least £450 from this concert. It is decided that the number of £3 tickets must not be greater than twice the number of £2 tickets. Write out three inequalities and show them on a graph. Hence find the number of £2 and £3 tickets which should be sold to obtain the maximum profit. State this profit.

Here’s your homework sheet.
