"950 feet in 19 minutes" can be expressed as the rate (950/19) (ft/min), and is negative because the diver is descending (going downward).
Simplifying, -950/19 (ft/min) = -50 (ft/min)
The standard form of an equation is

In the question, we have the following formula

To get the formula in standard form, we first have to subtract 2y from both sides (since we need to get 2y on the left side)

Finally we subtract 1 from both sides (since we need the number on the right side)

Hence, 4. is the correct answer.

Step-by-step explanation:
Let x be the number of sold children's tickets and let y be the number of adult tickets sold, then we can pose the following equations.
(i) Because 132 tickets were sold in total
(ii) because the total of $ obtained by sales was 931.20.
We must clear x. Then we substitute (i) in (ii)
