Answer:
A
Step-by-step explanation:
s = cost of senior ticket
c = cost of child ticket
System of Equations:
8s + 7c = 211
4s + 6c = 138
I used the elimination method and multiplied the second equation by -2
-8s - 12c = -276
add the above to the first equation and get
-5c = -65
c = 13
now find s
8s + 7(13) = 211
8s + 91 = 211
8s = 120
s = 15

Answer:
67.5
Step-by-step explanation:
2x = 15
x =7.5
9*7.5 = 67.5
Sales tax will result an increased priced. Since the increased rate is (1 + 6%) = 1 + 0.06 = 1.06. So the price will be
$13.74*(1.06) = $14.56
Answer :-
- loss = <em> </em><em>100</em><em>0</em><em>$</em><em> </em>
- 4000
Step by step explanation :-
1#
Profit on 3000 bags of white cement sold = 3000 × 8 = 24000
loss on 5000 bags of grey cement sold = 5000 × 5 = 25000
<u>Alternatively</u><u>:</u><u> </u>
- Net loss = ( 25000 - 24000 ) = 1000$
- profit/ loss = $ [3000 × 8 - 5000 × 5 ]
- $ [24000 - 25000]
- -1000$
<em>As</em><em> </em><em>the</em><em> </em><em>result</em><em> </em><em>of</em><em> </em><em>transaction</em><em> </em><em>is</em><em> </em><em>negative</em><em>/</em><em> </em><em>loss</em><em> </em>
2#
- Loss on the scale of 6400 grey bags = 6400 × 5 = 32,000
<em>In</em><em> </em><em>order</em><em> </em><em>to</em><em> </em><em>have</em><em> </em><em>no</em><em> </em><em>profit</em><em>, </em><em> </em><em>profit from the </em><em>Cello </em><em>white cement should be 32</em><em>0</em><em>0</em><em>0</em><em>.</em><em> </em>
- Number of white cement bags to be sold = 32000 / 8 = 4000
<em>4000 why cement bags and 6400</em><em> </em><em>grey</em><em> </em><em>cement</em><em> </em><em> </em><em>bags</em><em> </em><em>are sold in order to have no profit and </em><em>n</em><em>o</em><em> </em><em>loss </em>
