Perfume is sold in 2 different sized bottles. The 80ml is priced at £55 and 100ml is £67.50. By finding the the price per ml, determine which one is best value for money.

The best value for money is the perfume that has a 100 ml bottle because the price per ml is lower.

Step-by-step explanation:

To find which one is the best value for money, you need to find the price per ml in each case by dividing the price by the amount of ml:

-80 ml: 55/80=0.687

-100 ml: 67.50/100=0.675

According to this, the answer is that the best value for money is the 100 ml bottle because the price per ml is lower with £0.675 per ml and the 80 ml bottle has a price of £0.687 per ml.

50-38=12

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
