Answer:

A candy costs $6.75 and a bag of popcorn costs $7.25

Step-by-step explanation:

Let the cost of one 1 candy=$x

Let the cost of one bag of popcorn=$y

Now, Total Cost Per Item=Number of Item Bought X Price Per Unit Item.

If Nathaniel bought 4 candies and 10 bags of popcorn for a total of 99.50 dollars.

4x+10y=99.50

Grant bought 3 candies and 5 bags of popcorn for a total of 56.50 dollars.

3x+5y=56.50

Solving the two equations simultaneously

4x+10y=99.50    (I)

3x+5y=56.50     (II)

Multiply Equation (I) by 3 and Equation (II) by 4 to eliminate x

12x+30y=298.5

12x+20y=226

Subtracting

10y=72.5

y=$7.25

Now, from (II)

3x+5y=56.50

3x+5(7.25)=56.50

3x+36.25=56.50

3x=20.25

x=20.25/3=$6.75

Therefore a candy costs $6.75 and a bag of popcorn costs $7.25

Answer:

candy costs - $6.75

a bag of popcorn costs - $7.25
