Answer:
Number of small candles = 12
Number of large candles = 16
Step-by-step explanation:
Total candles = 28
x + y = 28 ---------------(I)
Cost of 'x' small candles = 4 *x = 4x
Cost of 'y' large candles = 6 *y = 6y
Total amount = $144
4x + 6y = 144 -------------(II)
Multiply equation (I) by (-4) and then add the equation. So, x will be eliminated and we can find the value of 'y'
(I) * (-4) -4x - 4y = -112
(II) <u> 4x + 6y = 144</u> {Now, add}
2y = 32
y = 32/2
y = 16
Plug in y = 16 in equation (I)
x + 16 = 28
x = 28 - 16
x = 12

Answer:
<h2>31 tickets</h2>
Step-by-step explanation:
Step one:
number of tickets sold
monday=14
tuesday=10
the number of tickets sold for Monday and Tuesday combined is
14+10= 24
step two:
we want to find how many tickets make 30%
so 30/100*24
0.3*24
=7.2 tickets,
Approximately 7 ticket
Therefore the total ticket is
14+10+7
=31 tickets
Use the symmetric property to flip the sides of the equation.
Divide everything by 5.
