Question 11338
this is an easy question to solve, once you get past all the english.


First let x = amount of candy required (at £5.80).


so, we have candy1 + candy2 = (mixture)...that is all there is to it!


so we have 5.80x + 7(2.40) = (7+x)*3.42
5.80x + 16.80 = 23.94 + 3.42x
2.38x = 7.14
x = 3


so, we need 3lb of the first candy.
