Question 1208016
<br>
The way the problem is presented, you are probably expected to use the equation from part (a) to answer part (b).<br>
However, the actual computation for inverse variation is easier if you simply use the fact that the product of the price and the number of bags is constant.<br>
So, in this example....<br>
2.75(156) = 3.00(x)
x = 2.75(156)/3 = 2.75(52) = 104+39 = 143<br>
ANSWER: 143 bags<br>
A different easy way to do the computation is to use the fact that the ratio of numbers of bags is the reciprocal (inverse) of the ratio of prices.<br>
The price changes by a factor of 3.00/2.75 = 12/11; the number of bags must change by a factor of 11/12:<br>
156(11/12) = 11(13) = 143<br>
