Step-by-step explanation:

Remember to follow PEMDAS, the order of operation.

PEMDAS =

Parenthesis

Exponents (& roots)

Multiplications

Division

Addition

Subtraction

First, plug in 2 for x, and 4 for y

(2(2) + 3(4))/4 - 2

Simplify:

2 * 2 = 4

3 * 4 = 12

4 + 12 = 16

16/4 = 4

4 - 2 = 2

2 is your answer.

If there are tickets sold to children for $5 and $12 to adults, and there are only 400 tickets sold for $3925 then how many chil

Sever21 [200]

125 children tickets were sold

Solution:

Given that

Price of 1 ticket sold to children = $5

Price of 1 ticket sold to adult = $12

Total number of ticket sold = 400

Amount generated by selling 400 tickets = $3925.

Need to calculate number of ticket sold to children’s

Let’s assume number of tickets sold to childrens = x

So number of tickets sold to adults = 400 – x

Amount generated from x ticket sold to children $=x \times \text { Price of } 1 \text { ticket sold to children }$

$x \times 5=5 x$

Amount generated from (400 – x) tickets sold to adults $=x \times \text { Price of } 1 \text { ticket sold to adult }$

$=(400-x) \times 12=4800-12 \mathrm{x}$

Total amount generated from 400 tickets = Amount generated from children’s tickets + Amount generated from adults ticket

= 5x + (4800 – 12x) = 4800 -7x

As given that amount generated = 3965

=> 3965 = 4800 – 7x

Solving above expression to get value of x, we get

7x = 4800 - 3965

=> 7x = 875

=> x = 125.

Hence number of children tickets sold = 125.
