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>
Heather winning, so the probability that Isabelle will win is : 1 whole right ?
16/81 = 65 over 81
Answer:
Hello! answer: 85
Step-by-step explanation:
68 × 68 = 4624
51 × 51 = 2601
4624 + 2601 = 7225
√7225 = 85
85 × 85 = 7225 therefore c = 85 Hope that helps!
