A vendor sells hot dogs, bags of potato chips, and soft drinks. A customer buys 4 hot dogs, 3 bags of potato chips, and 4 soft d

GuDViN [60]

The price of chips is $ 0.75, the price of a hot dog is $ 2 and the price of a soft drink is $ 1.25.

Step-by-step explanation:

Given,

A customer buys 4 hot dogs, 3 bags of potato chips, and 4 soft drinks for $15.25.

The price of a hot dog is $1.25 more than the price of a bag of potato chips.

The cost of a soft drink is $2.75 less than the price of two hot dogs.

To find the cost of each item.

Let,

The price of chips = x

The price of a hot dog = x+1.25

Price of two hot dog = 2(x+1.25) = 2x+2.5

The price of a soft drink = 2x+2.5-2.75 = 2x-0.25

Now,

According to the problem,

4(x+1.25)+3x+4(2x-0.25) = 15.25

or, 15x+5-1 = 15.25

or, 15x = 11.25

or, x = 0.75

Hence,

The price of chips = $ 0.75

The price of a hot dog = $ 0.75+1.25 = $ 2

The price of a soft drink = $ 2×0.75-0.25 = $ 1.25

Answer:

x=-10, y=-20

Step-by-step explanation:

Since both 2x and 3x+10 equals y, they equal each other.

2x = 3x + 10

x = -10

Substitute -10 for x

2(-10) = y

y=-20

Lincoln went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 250 mg of sodium and each

Ludmilka [50]

We can solve with a system of equations, and use c for the amount of cans of soup and f for the amount of frozen dinners.

The first equation will represent the amount of sodium. We know the (sodium in one can times the number of cans) plus (sodium in one frozen dinner times the number of dinners) is the expression for the total sodium. We also know the total sodium is 4450, so:

250c + 550f = 4450

The second equation is to find how many of each item are purchased:

c + f = 13

Solve for c in the second equation:

c = 13 - f

Plug this in for c in the first equation:

250(13-f) + 550f = 4450

3250 - 250f + 550f = 4450

300f = 1200

f = 4

Now plug the value for f into the second equation:

c + 4 = 13

c = 9

The answer is 9 cans of soups and 4 frozen dinners.
