Jamie has organised a last minute camping trip with his friends before they go back to school next week.
Jamie buys packs of sausages and packs of burgers for the trip in the ratio 3 : 4.
The cost of a pack of sausages is 75% of the cost of a pack of burgers.
Jamie buys 16 packs of burgers.
Each pack of burgers costs £x.
He spends £125.00 in total.
How much does Jamie pay for each pack of sausages?
Answer:
Ratio of sausages to burgers = 3 : 4
So, if there are 16 packs of burgers there will be 12 packs of sausages.
If we let x = burger price, then 0.75x = sausage price.
Total price of food = 16x + 12(0.75x)
125 = 16x + 9x
125 = 25x
Price of 1 pack of burgers = £5
0.75x is the price of a pack of sausages.
So, the price of a pack of sausages is 0.75 x 5 = £3.75
