Answer:
A-75 and B-25
Step-by-step explanation:
Firstly, divide the 200 students by the amount of sections (8) and that gives you 25 a section. Since year 7 has 3 sections and year 9 has 1, 3(25)=75 and 25(1)=25.
I think what you meant to type is "markup". If the markup is 6.5%, we need to increase the cost by that amount. To find 6.5% of a number we convert it to a decimal, .065, and we add 1.00, to get 1.065. The 1, when multiplied, gives us the original amount, and the .065 gives us the additional amount. We multiply that by 784.5. 784.5 x 1.065 = 835.49. The other way to do it is to just multiply by 0.065, and you get 784.5 x 0.065 = 50.99, then add it to the original amount, 784.5 + 50.99 = 835.49.
