Agrocery store sells three different quantities of sugar. a pound bag costs $1.10, a 2 pounds of a bag costs $1.98,and a 3 pounds of a bag costs $2.85. describe how the unit cost changes as the quantity of sugar increases.

3 qrs + 3/2 xy hope this : /

step-by-step explanation:

  or  

sin y = 7/q

7 is the opposite side length, q is the hypotenuse

tan y = 7/r

7 is the opposite side length, r is the adjacent side length

using sohcahtoa ^^^^

cos y = adjacent/hypotenuse

cos y = r/q

the one where 1 and 2 are directly across from each other.
