Answer:
$7.5
Step-by-step explanation:
To solve this problem, we first have to find out how much Tu spent and then subtract that from the total amount that Tu gave the clerk.
TOTAL AMOUNT SPENT
2 tickets at $9.5 each = 2 * 9.5 = $19
Popcorn for $5 = $5
2 drinks at $4.25 each = 2 * 4.25 = $8.5
Total = $19 + $5 + $8.5 = $32.5
TOTAL AMOUNT GIVEN TO CLERK
He gave the clerk two $20 bills = 2 * 20 = $40
Hence,the change he will collect will be:
$40 - $32.5 = $7.5
Tu collected $7.5 change from the clerk.
Let <em>x</em> be the number of one-striped fish and <em>y</em> the number of two-striped fish.
100 families each have 2 fish, so there are a total of 200 fish:
<em>x</em> + <em>y</em> = 200
<em>x</em> one-striped fish carry a total of <em>x</em> stripes, while <em>y</em> two-striped fish carry a total of 2<em>y</em> stripes. There are 273 stripes overall, so
<em>x</em> + 2<em>y</em> = 273
Solve for <em>x</em> and <em>y</em>. Subtracting the first equation from the second eliminates <em>x</em> :
(<em>x</em> + 2<em>y</em>) - (<em>x</em> + <em>y</em>) = 273 - 200 ==> <em>y</em> = 73
Then
<em>x</em> + 73 = 200 ==> <em>x</em> = 127
