Let x be the number of pounds needed from the 1.65 candy.

We have the following

Type 1 + Type 2 ----> Mix

x lb (100-x)lb 100lb

$1.65/lb $1.90/lb $1.75/lb

If we look at the cost of moxing the candy we get the following.

`1.65*x+1.90(100-x)=1.75*100`

`1.65x+190-1.90x=175=>`

`-0.25x=-15=>x=60`

**Hence we need 60lb of the $1.65 candy and 40lb of the $1.90 candy.**
