Answer:
= 2(1 - 2h)
Step-by-step explanation:
Given that:
=3(2−0.9h)+(−1.3h−4)
Simplifying:
=(6 - 2.7h) + (-1.3h - 4)
Removing brackets
=6 - 2.7h -1.3h - 4
Adding like terms (h terms and constants)
= 2 - 4h
We can take 2 common as:
= 2(1 - 2h) Required sum

Let x be the number of child admission tickets sold:
Child's ticket = x
There is a total of 145 tickets sold:
Adult = 145 - x
Total sales is $1020.80:
5.6x + 9.2(145 - x) = 1020.8
Solve for x:
5.6x + 9.2(145 - x) = 1020.8
5.6x + 1334 - 9.2x = 1020.8
3.6x = 313.2
x = 313.2 ÷ 3.6
x= 87
Answer: Number of child's ticket = 87
Hey there!!
