He needs 100g of the 21% alloy, and 0g of the 15% alloy to attain the 100g of 21% titanium.
It's the 3rd graph that represents a linear rel. Notice that each time x increases by 1, f(x) increases by 2. Thus, the slope is 2 and the equation of the line in the 3rd graph is y = 2x - 1.
<span>52/x = 9.5/3.25
9.5x = (52)(3.25)
9.5x = 169
x = 17.8
