Jane made 720 biscuits for a fete. She sold 70% of them at 25p each.
She sold the other 30% at 4 for 60p.
The biscuits cost her £40 to make.
Calculate her percentage profit.

296%

Step-by-step explanation:

Total number of biscuits sold = 720

70% of 720 = 0.7 x 720

                   = 504

Amount of 504 biscuits sold = 504 x 25p

                             = 12600p

But 100p = £1

So that,

12600p = £126

30% of 720 = 0.3 x 720

                    =  216

But, she sold 216 biscuits at 4 for 60p.

The amount of 216 biscuits sold = x 60p

                                      = 54 x 60p

                                      = 3240p

                                      = £32.40

Total amount on sales = £126 + £32.40

                            = £158.40

But her cost price is £40.

Profit = £158.40 - £40

         = £118.40

Her percentage profit = x 100

                                    = 296%
