425.69+298.72=724.41
29.72+135.47+208.28=373.47
724.41-373.47=350.94
350.94-5=345.94
The answer is c
Three hundred thousand four thousand one
300000 +4000+1
To solve this you will need to take 90-15=75 then take 75/3=25 so a biscuit costs 25p and a cake costs 40p becuase 25*2=50+40=90 enjoy!=)
Just look at the percentages and make them into fractions. You can think about it like money. 50 cents is half of a dollar, so %50 is 1/2. for the decimals, you just take the percent and put a decimal point in front of the answer, so 28% is .28, 50% is .50, 18% is .18. For fraction to decimals, you could just put 1 divided by 4 into a calculator and it will tell you .25, which is the decimal, and 25 cents is one fourth of a dollar, so it works out.
Hope this helps! Let me know if you have any more questions!
