Answer:
$8 for Senior Citizens
$12 for Students
Step-by-step explanation:
Let C be the price of a senior citizen ticket
Let S be the price of a student ticket.
We are told that, on the first day, that:
7C + 4S = $104
On the second day:
7C + 1S = $68
We have 2 equations and 2 unknowns. Rearrange either equation to express one of the unknowns in terms of the other
For example:
7C + 1S = $68
S = $68 - 7C
Now use this value of S in the other equation:
7C + 4S = $104
7C + 4($68 - 7C) = $104
7C + $272 - 28C = $104
-21C = - $168
<u>C = $8 for a Senior Citizen ticket</u>
We can use C = $8 in either equation to find S.
S = $68 - 7C
S = $68 - 7($8)
S = $12
<u>Student tickets are $8 each</u>
=====
See if these values work in the original equations:
1. 7C + 4S = $104
7($8) + 4($12) = $104 ?
$56 + $48 = $104 <u>YES</u>
2. 7C + 1S = $68
7($8) + 1($12) = $68 ?
$56 + $12 = $68 <u>YES</u>
Answer:
A. <ECF and <BCF
Step-by-step explanation:
Complementary angles are angles that add up to give 90°
m<BCE = m<BCA = 90° (right angles)
m<ECF + m<BCF = m<BCA
m<ECF + m<BCF = 90° (Substitution)
Therefore, <ECF and <BCF are complementary angles.
