tickets for a football match are sold at $30 for adults and $15 for children a company bought 28 tickets
if x of these tickets were for adults, write in terms of x
a. the number of tickets for children
b. the amount spent on tickets for adults

d show that the total amount spent on the 28 tickets is $(15x+420)
e. given that the cost of the 28 tickets was $660, calculate the number of adult tickets bought by the company

These questions almost answer themselves. For example:
a) 28  x
b) 30 x
c) 15(28 x)
d) 30x +15(28x) = _____
e) Solve 15x + 420 = 660 to get x
Do some thinking; show your work. 
for (e) is the answer correct if i get a decimal number like 8.5?
