Answer:
21
Step-by-step explanation:
3(8)-12=12
24-12=12
The fourth choice.
Yeah I think you already got it
The rule is you must multiply by three.
For number 12 you need to make an expression using the information given. a) 25g + 18r + 15b could be the expression.
b) The variables would be 25g for the 25 gold seats, 18r for the 18 red seats and 15b for the 15 blue seats.
c) Plug in the number given according to the variables.
25(100) + 18(250) + 15(200)
2500 + 4500 + 3000
7000 + 3000
$10,000
When two equations are given, there are many operations in which you can do involving both as long as the variables (independent and dependent) are similar to both equations. In this case, we can directly apply operations to both equations since both functions are functions of x. The largest coefficient of the x term would be achieved by multiplication since using distribution property, the coefficient of x would be 6. Subtraction or addition would only lead to less number (0 and 4 respectively). Division is not applicable as there are no factors similar to both functions which can be cancelled to each other. Answer then to this problem is multiplication.
