:
A peach weighs 65 grams. If you buy 10 peaches and they sell for $5.50 per kilogram, how much will they cost?
:
Find how many grams for 10 peaches: 10 * 65 = 650 gram
:
Change to kilograms, divide by 1000: {{{650/1000}}} = .65 kilograms
:
Find the cost of .65 kilos at $5.50 per kilo: .65 * 5.50 = $3.58
:
In one equation: Cost = {{{((10*65))/1000}}} * 5.50 = 3.575</PRE>
