Answer:
Part a) The equation that determine the original price per pound is equal to [tex]3(p+0.75)=5.88[/tex]
Part b) The original price per pound is [tex]\$1.21[/tex]
Step-by-step explanation:
Let
p-----> the original price per pound
x-----> the new price per pound
we know that
[tex]x=p+0.75[/tex] -----> equation A
[tex]3x=5.88[/tex] ----> equation B
substitute equation A in equation B
[tex]3(p+0.75)=5.88[/tex] -----> equation that determine the original price per pound
solve for p
[tex]3p+2.25=5.88[/tex]
[tex]3p=5.88-2.25[/tex]
[tex]3p=3.63[/tex]
[tex]p=3.63/3=\$1.21[/tex]
Answer:
For the first one, it's: 3(p+0.75)=5.88
And for the second answer, it's: $1.21
