1. Firstly, you've got to find 1% and multiply this by 7. You do this by dividing $14.67 by 100. 14.67/100= 0.1467. 0.1467x7= 1.0269 (1.03 rounded) You then add these together, and this gives you $15.70
2. For this, you've got to add the percentage decrease (10/.01) to 1, and then multiply $45.26, and this gives you $49.786 (essentially $50 rounded)
3. You've got to divide the smaller number (43.20) by the larger number (180), and this gives you 0.24, and you've then got to multiply this by 100, giving you 24%. Therefore, he received a 76% discount.
4. The best thing to do here is to divide the larger number (300) by the smaller number (5), and this gives you 60, therefore, the average speed of the train is 60 miles per hour.
