Answer:
Step-by-step explanation:
1) Number of children = c
Number of adults = a
Total ticket = 250
c + a = 250 -------------------(I)
Cost of 'c' children tickets = 200c
Cost of 'a' adult tickets = 450a
Total cost = 76000
200c + 450a = 76000 ------------------(II)
Multiply (I) by (-200) and then add
(I)*(-200) -200c - 200a = -50000
(II) <u> 200c + 450a = 76000 </u>
<u> </u> 250a = 26000
a = 26000/250
a = 104
Plug in a = 104 in equation (1)
c + 104 = 250
c = 250 - 104
c = 146
2)Number of children = 146
Number of adults = 104
The amount Sheila deposits in the Bank of US saving account is $511.
Sabrina has a total of $3,066 she wants to deposit. She has three banks that she wants to deposit her money in.
Let, a represent the amount she would deposit she would invest 7/4 bank.
The amount invested in Catch bank = 6 x a = 6a
The amount invested in Bank of US = 20% x ( 6a + a)
= 0.2 x 7a
= 1.4a
The total amount invested in the three banks can be represented with this equation:
1.4a + a + 6a = 3066
In order to determine the amount she would save in the Bank of US, the amount deposited in 7/4 bank has to be determined first.
8.4a = 3066
a = $365
The amount deposited in the Bank of US = 1.4a
= 1.4 x 365
= $511
