Hello!

This all isn't very complicated, but requires some work.

Probably you know that if we take the same number (x) several times (n) and have to sum them up, then the result is x*n (x multiplied by n), or n*x (the same). Now go for specific questions.

1.a. 16 adults, each have to pay 9.48. The total cost is 16*9.48 = 151.68.

1.b. 25 children by 4.74, 25*4.74 = 118.50.

1.c. 40 children and 6 teachers (probably adults): 40*4.74 + 6*9.48 = 246.48.

1.d. 2 adults, 2 children and 1 car: 2*9.48 + 2*4.74 + 5.25 = 33.69.

1.e. 12 adults, 33 children and 1 coach: 12*9.48 + 33*4.74 + 31.50 = 301.68.

2.a. 35 adults and 1 coach: 35*9.48 + 31.50 = 363.30.

2.b, c. How much cars it is necessary for 35 adults? No less than 35/4 = 8.75, i.e. 8 is insufficient but 9 is sufficient (4*9 = 36).

So there are 35 adults and 9 cars. But we don't want to sum this, the question is this more or less than in 2.a?

The same number of adults for both options, the difference is in transport only. 1 coach costs 31.50 and 9 cars cost 9*5.25 = 47.25, so the car variant costs more. The difference is 47.25 - 31.50 = 15.75.
