quester [9]

Answer: 20

Step-by-step explanation:

Given

The cost of an individual ticket is $25

The cost of a couple's ticket is $40

The total sale is $2500

total ticket sold is 70

Suppose there are x individuals and y couples

\therefore x+y=70\quad \ldots(i)\\\\25x+40y=2500\quad \ldots(ii)\\\text{Solving }(i)\ \text{and}\ (ii)\ \text{we get}

x=20,y=50

So, they sold 20 tickets of the individual.

-6.2 - 12.6x = 5.8 - 7.8x
Sav [38]

Answer:

x = -2.5

Step-by-step explanation:

Step 1: Write equation

-6.2 - 12.6x = 5.8 - 7.8x

Step 2: Solve for <em>x</em>

<u>Add 12.6x on both sides:</u> -6.2 = 5.8 + 4.8x

<u>Subtract 5.8 on both sides:</u> -12 = 4.8x

<u>Divide both sides by 4.8:</u> x = -2.5

Step 3: Check

<em>Plug in x to verify if it's a solution.</em>

-6.2 - 12.6(-2.5) = 5.8 - 7.8(-2.5)

-6.2 + 31.5 = 5.8 + 19.5

25.3 = 25.3
