Answer:
Hotdog costs $5.35 each and hamburger costs $0.18 each
Step-by-step explanation:
The difference in price between the two is the cost of 5 hotdogs.
So, $56.25 - $29.50 = $26.50
I hotdog would cost $26.50/5 = $5.35
Substituting the cost of one hotdog,
10($5.35) + 15ham = $56.25
$53.50 + 15 ham = $56.25
15 ham = $56.25 - $53.50
15 ham = $2.75
So, 1 ham = $2.75/15
= $0.18

Answer:
271 people
Step-by-step explanation:
Margin of error = critical value × standard error
At 90% confidence, the critical value is 1.645.
Standard error for a proportion is s = √(p (1 − p) / n).
0.05 = 1.645 √(0.52 (1 − 0.52) / n)
n = 271
