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

<u>Solution</u>:

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 $=x \times \text { Price of } 1 \text { ticket sold to adult }$

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

<em>Total amount generated from 400 tickets = Amount generated from children’s tickets + Amount generated from adults ticket </em>

= 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.

Corinne bought 5 bags of chips and 4 jars of dipping sauce for $21.82. At the same prices, Ginger bought 4 bags of chips and 3 j

AURORKA [14]

Step-by-step explanation:

5 bags of chips and 4 jars of dipping sauce cost $21.82. Also, 4 bags of chips and 3 jars of dipping sauce cost $16.86.

This problem can be modeled using linear equations in two variables.

Let $c$ be the cost of a bag of chip and $s$ be the cost of a jar of dipping sauce.

The information yields the equations

$5c+4s=21.82,4c+3s=16.86\\\textrm{Multiply first equation by 4 and second equation by 5}\\20c+16s=87.28,20c+15s=84.3\\\textrm{Subtracting second equation from the first one}\\s=\$2.98$

∴ A jar of dipping sauce costs $\$2.98$ .

Given ABC=65 and BCD=105. Is it possible that Line AB intersects line CD

levacccp [35]

Given:

$m\angle ABC=65^\circ$

$m\angle BCD=105^\circ$

To find:

Whether it is possible that Line AB intersects line CD.

Solution:

We have,

$m\angle ABC=65^\circ$

$m\angle BCD=105^\circ$

The angles $m\angle ABC$ and $m\angle BCD$ are same sided interior angles.

If two lines are parallel and a transversal line intersect them, then the same sided interior angles are supplementary angles and their sum is 180 degrees.

$m\angle ABC+m\angle BCD=65^\circ+105^\circ$

$m\angle ABC+m\angle BCD=170^\circ$

$m\angle ABC+m\angle BCD\neq 180^\circ$

So, the lines AB and CD are not parallel to each other.

Therefore, the intersection of lines AB and CD is possible.
