Answer:
Part a) The equation that determine the original price per pound is equal to ![3(p+0.75)=5.88](https://tex.z-dn.net/?f=3%28p%2B0.75%29%3D5.88)
Part b) The original price per pound is ![\$1.21](https://tex.z-dn.net/?f=%5C%241.21)
Step-by-step explanation:
Let
p-----> the original price per pound
x-----> the new price per pound
we know that
-----> equation A
----> equation B
substitute equation A in equation B
-----> equation that determine the original price per pound
solve for p
![3p+2.25=5.88](https://tex.z-dn.net/?f=3p%2B2.25%3D5.88)
![3p=5.88-2.25](https://tex.z-dn.net/?f=3p%3D5.88-2.25)
![3p=3.63](https://tex.z-dn.net/?f=3p%3D3.63)
![p=3.63/3=\$1.21](https://tex.z-dn.net/?f=p%3D3.63%2F3%3D%5C%241.21)
Answer:
37.68
Step-by-step explanation:
A= 3.14 x 4 x 4 = 50.24
50.24 ÷ 4 = 12.56
12.56 x 3 = 37.68
it is a not linear may help u
