You and your friends go to the fair and spend $35 on 10 hot dogs and 5 drinks if the concession stand is advertising seven hot dogs and four drinks for $25.25 what is the cost for one hot dog and one drink.

So for this, you will be doing a system of equations. The first equation will be how much you spent and the second equation is how much they advertise.

Let h = cost of hotdog and d = cost of drinks

With this, i'll be using the substitution method. So firstly, subtract 10h on each side of the first equation. It will look like this:

Next, divide 5 on each side of the first equation. Your answer will be

Next, replace d in the second equation with (7-2h). Your second equation will look like this: . From here you can solve for h.

Firstly, foil 4(7-2h).

Next, combine like terms:

Next, subtract 28 on each side to get

Lastly, multiply -1 on each side of the equation to get

Now that we got h, we can solve for d by substituting 2.75 in the h variable in either equation. For this, I'll be using the first one.

In short, hotdogs are $2.75 each and drinks are $1.50 each.

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
