Craig has £13.40 he sees this offer in a restaurant : main courses £8.90 each. buy one main course and get the second half price. can he afford to buy two main courses? show your working

Yes

Step-by-step explanation:

Full price for first course:  £8.90

Half price:                           £4.45

One and one half times

 full price is then:             £13.35

Since this is less than Craig's £13.40, he can just barely afford to buy two main courses at these prices.

f(x) has value 150 at x= 0

and 0 at x= 3

so d(f(x))/dt = slope = -150/3 = -50
