If three Magnums and two Paddlepops cost $8.70 and the difference in price between a Magnum and a Paddlepop is 90 cents, how muc
sveticcg [70]

Answer:  Magnum = $2.10

               Paddlepop = $1.20

<u>Step-by-step explanation:</u>

Let M represent Magnum and P represent Paddlepop, then create a system of equations using the cost as one equation and the difference in price as the other.  Use the elimination method to solve for one of the variables and substitution to solve for the other.

3M + 2P = 8.70   →   1(3M + 2P = 8.70)   →   3M + 2P = 8.70

 M  -  P  = 0.90   →   2(M  -  P  = 0.90)    →   <u>2M  - 2P = 1.80   </u>

                                                                      5M         = 10.50

                                                                        M          =  2.10

 M  - P = 0.90

2.10 - P = 0.90

       -P = -1.20

        P = 1.20
