A baker uses chocolate with 75% cocoa for his famous cake. But his supplier delivered 100 lb of chocolate with 70% cocoa, so the baker needs to melt and mix the delivery with chocolate that has 90% cocoa. How much of the 90% chocolate should he use?
Answers
33 1/3 BTW i am from RSM too :)
33.33 lb of 90% cocoa cholcolate should be mixed.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given here: A baker has to mix 70% cocoa with 90% cocoa and he has 100 lb of the first chocolate.
let x lb of chocolate be mixed with 100 lb to give the 75 % chocolate variety
Thus, x×90%+100×70% / 90%+70% = 75%
0.9x+70 /x+100=0.75
0.9x+70=0.75x+75
0.15x=5
x=33.33
Thus 33.33 lbs of 90% cocoa should be mixed to get 75% cocoa
Hence, 33.33 lb of 90% cocoa cholcolate should be mixed.

Gloria subscribes to the Webtime Internet Service. Webtime charges a $9.99 monthly service fee plus $1.50 per hour for Internet access.
Total bill = $9.99 + $1.50 × x
= 9.99 + 1.5x
Last month's bill was $ 36.99.
Hence,
9.99 + 1.5x = 36.99
Collect like terms
1.5x = 36.99 - 9.99
1.5x = 27
x = 27/1.5
x = 18 hours
