4/3 = 1/x.....4 lbs potatoes to $3 = 1 lb of potatoes to $x
cross multiply
(4)(x) = (3)(1)
4x = 3
x = 3/4
x = 0.75....so 1 lb of potatoes cost 75 cents
(8,6)...this means 8 lbs of potatoes cost $6
To be honest I just know that #1 is 143 (I think)
D) square the number and add 2

If that's an addition sign, then b=-35.
If it's a division sign, then b=-150
Sorry I can't see which it is! Hope this helped though :)
Good luck!
