Ahoneydew melon costs four times as much as a peach. together they cost $1.50. how much does each cost

Cost of peach = 0.30$

Cost of honeydew melon = 1.20$

Explanation:

 Let us assume that cost of peach to be x.

 So we have cost for the honeydew melon = Four times of the cost of peach

                                                                        = 4x

   Total cost = Cost of honeydew melon +  Cost of peach

                    = 4x+x = 5x

   We also have total cost = $1.50

   So equating both

               5x = $1.50

                 x = 1.50/5 =0.30$

   So cost of peach = 0.30$

        Cost of honeydew melon = 4x = 4*0.30 = 1.20$

28j + 21

Step-by-step explanation:

combine like terms

7(2j+ 3+ 2j)

7(4j+3)

Distribute

7(4j + 3)

=

28j + 21
