Answer:
The price of hot dog is $2.5 and that of a pretzel is $1.25.
Step-by-step explanation:
Let the cost of hotdogs be h and that of pretzels be p.
So,
4h+3p = 13.75 ...(1)
and
2h+5p = 11.25 ...(2)
Multiply equation (2) by 2.
4h+10p = 22.5 ...(3)
Subtract equation (1) from (3).
4h+10p-(4h+3p) = 22.5-13.75
4h+10p-4h-3p = 8.75
7p = 8.75
y = 1.25
Put the value of y in equation (1).
4h+3(1.25) = 13.75
4h+3.75 = 13.75
4h = 13.75-3.75
4h = 10
h = 2.5
So, the price of hot dog is $2.5 and that of a pretzel is $1.25.

B I aplogize if its wrong i haven't done this type of math in a couple years so its foggy
Hope it Helps!
Answer:
1. No, 2. 46, 3. The amount of tails flips would be more than the amount of heads flips.
Step-by-step explanation:
1 is no because .77 and .23 are not equal to .5, so her prediction was wrong. 2 is 46 because if you double both the numbers (to get a total of 200 flips), you would get 154 tails and 46 heads. 3 is more tails than heads because that is what we have observed.
