The fraction of marbles in the box that is green = ⁷/₍₅₊₇₊₈₎
                                                                               
                                                                                =  ⁷/₂₀

If there are 240 marbles in the box, then the number of green marbles = (240 × ⁷/₂₀) = 84 marbles

∴ 84 of the marbles in the bag are green.

Mrs Lim bought a number of plates at an average price of $6. She decided to buy another plate which cost $18. The average price
soldi70 [24.7K]

Answer:  6

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

Let x represent the number of plates bought for $6

Let y represent the Total number of plates bought = x + 1

<em>Remember that Mrs. Lim bought another plate for $18</em>

Total cost ÷ Total plates = Average Cost

\dfrac{6x+18}{x+1}=8\\

6x + 18 = 8(x + 1)

6x + 18 = 8x + 8

       18 = 2x + 8

       10 = 2x

        5 = x

y = x + 1

  = 5 + 1

  = 6
