To make his famous chocolate cake, a baker uses chocolate that is 75% cocoa.
Because his supplier delivered 100lbs of 70% cocoa, the baker needs to melt and mix this with chocolate that is 90% cocoa to make this cake. How much of this 90% chocolate should he use?

(answer) pounds


Sagot :

The baker needs to use 100/3 pounds of 90% chocolate to make the cake.

Equation

An equation is an expression used to show the relationship between two or more numbers and variables.

Let x represent the amount of 90% chocolate. Using equation:

100 * 70% + x * 90% = (x + 100) * 75%

100 * 0.7 + 0.9 * x = (x + 100) * 0.75

70 + 0.9x = 0.75x + 75

x = 100/3

The baker needs to use 100/3 pounds of 90% chocolate to make the cake.
