To find the unit rate, you have to find how much each pound costs
so 14.25/3 is the expression that will get you the answer
14.25/3= 4.75
4.75 per pound is your answer
hope this helps
3x-10+2x=115
5x-10=115
5x=125
x=25
m<b=3(25)-10=65
m<C=2×25=50
y=5/6+3
I am not positive on this answer I am sorry if it is wrong
