Step-by-step explanation:
Number of child tickets bought is 20
<h3><u>
Solution:</u></h3>
Given that It cost 5 dollars for a child ticket and 8 dollars for a adult ticket
cost of each child ticket = 5 dollars
cost of each adult ticket = 8 dollars
Let "c" be the number of child tickets bought
Let "a" be the number of adult tickets bought
Total tickets sold were 110 bringing in 820 dollars
<em>Number of child tickets bought + number of adult tickets bought = 110</em>
c + a = 110 ----- eqn 1
<em><u>Also we can frame a equation as:</u></em>
Number of child tickets bought x cost of each child ticket + number of adult tickets bought x cost of each adult ticket = 820

5c + 8a = 820 -------- eqn 2
Let us solve eqn 1 and eqn 2 to find values of "c" and "a"
From eqn 1,
a = 110 - c ------ eqn 3
Substitute eqn 3 in eqn 2
5c + 8(110 - c) = 820
5c + 880 - 8c = 820
-3c = - 60
c = 20
Therefore from eqn 3,
a = 110 - 20 = 90
a = 90
Therefore number of child tickets bought is 20
Answer:
Mrs. Buggie should have Subtracted 13 instead of adding 13
LKA = 94°
Step-by-step explanation:
Lets work backwards from the equation so far:
40 = x+ 13
x + 13 = 40
We should subtract 13 because we are adding a number and 13 to 40
Imagine this:
You have 5 apples, but you bought some more and now you have 10
equation would be:
5+x = 10
subtract 5 from 10 to get 5
So you bought 5 apples
Back to the Question:
40 - 13 = 27
3(27) + 13 = 81+13 = 94°
Answer = 94°
