yes sure, i learned this before so
1. a. make a proportion here, of percentage. [tex] \frac{225}{250} =\frac{x}{100} [/tex] if you cross multiply and divide you get 90%.
1. b. obviously the empty seats would be 10%.
2. a. proportion again, [tex] \frac{0.90}{6.00} =\frac{x}{100} [/tex] cross multiply then divide you ge 15%
3. 30% in decimal form is 0.3. multiply it then to the total amount, so 0.3 x 15 = 4.5
