Answer:
45 + ( 7.50*x)
Step-by-step explanation:
I believe the answer is:
45 because you start with it costing that much and then the 7.50x because each child costs 7.50 and you don't know how many there will be.
10.4 :)
(16a + 6b) (2x - 3y)
32ax + 12bx - 48ay - 18by
(32ax - 48ay) + (12bx - 18by)
16a(2x - 3y) + 6b(2x - 3y) Factor out in both seperate expressions
(16a + 6b) (2x - 3y) Double factoring
your answer is 75.4
