Q. The cost to produce 1010 key rings is £2.40 £ 2.40 \newlineThe cost to produce 88 bangles is £2.40 £ 2.40 \newlineKey rings are sold in boxes of 200200 for £60 £ 60 \newlineBangles are sold in baxes of 400400 for £140 £ 140 \newlineHow much more profit is made on a box of bangles than on a box of key rings?
  1. Calculate cost per key ring: Calculate the cost per key ring.\newline£2.40/10\pounds 2.40 / 10 key rings = £0.24\pounds 0.24 per key ring.
  2. Calculate cost per bangle: Calculate the cost per bangle.\newline£2.402.40 / 88 bangles = £0.300.30 per bangle.
  3. Calculate total cost for 200200 key rings: Calculate the total cost for 200200 key rings.\newline200200 key rings ×£0.24=£48\times \pounds0.24 = \pounds48.
  4. Calculate total cost for 400400 bangles: Calculate the total cost for 400400 bangles.\newline400400 bangles ×£0.30=£120\times \pounds0.30 = \pounds120.
  5. Calculate profit for box of 200200 key rings: Calculate the profit for a box of 200200 key rings.\newline£60−£48=£12£60 - £48 = £12.
  6. Calculate profit for box of 400400 bangles: Calculate the profit for a box of 400400 bangles. £140−£120=£20£140 - £120 = £20.
  7. Calculate difference in profit: Calculate the difference in profit between a box of bangles and a box of key rings.\newline£20−£12=£8£20 - £12 = £8.
