if you plug in the values in this case, you would then solve (10-5)/-5+2

this equals 5/-3, or -5/3

At the city museum, child admission is $5.60 and adult admission is $9.20. On Sunday, 145 tickets were sold for a total sales of

Studentka2010 [4]

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

We divide both sides by 2 to isolate x...
x > 23
There you go. Any number greater than 23 is a correct answer to your problem. Let's verify by substituting x for 24.
2(24) + 3 > 49
48 + 3 > 49
51 > 49 </span>
