My friend is obviously wrong. If I'm paying $2.40 for three fourths of a pound, what makes him think that he'll pay less for more grapes? This equation actually doesn't involve any equations.
147 * 1.60 -> this way is an all in one calculation but to double check you can take 60% of 147 (147 * .60 = x ) and add that value to 147 so... 88.2+147=235.2
