Harold spend $7.65 on apples. #### Explanation: So if I'm reading this question right, both kinds of apples cost $0.17 cent a pound then you need to multiply it in two equations or just one question.

First Method:

Red Apples - $0.17 \cdot 3 = 0.51$
Green Apples - $0.17 \cdot 42 = 7.14$

Total Cost - $7.14 + 0.51 = 7.65$

Second Method

You could of added the pounds of red apples with green apples as they cost the same amount of per pound so

$42 + 3 = 45$

So there is 45 pounds of apples together that cost the same price per pound which is $0.17$ so we can multiply this by 45 like this:

$0.17 \cdot 45$

Our final answer gives us $7.65$ the same answer as the first method of doing it.
