Sabrina was able to map circle P onto circle R (with Q and S being on each circle, respectively) using a translation and a dilat
ion.
Sabrina concluded: "I was able to map circle P onto circle R using a sequence of rigid transformations and a dilation, so the figures are similar."
What error did Sabrina make in her conclusion?
A. Sabrina used a translation, so the circles aren't similar.
B. Sabrina used a dilation, so the circles aren't similar.
C. There is no error. This is a correct conclusion.

the cost for each of jelly beans and each pound of trail mix is $2.5 and $1.75
<u>Step-by-step explanation:</u>
Given A store is having a sale on jelly beans and trail mix. For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is $11. For 5 pounds of jelly beans and 6 pounds of trail mix, the total cost is $23 . We have to find the cost for each pound of trail mix and each pound of jelly beans.
Let the cost of each pound of trail mix is $y.
and the cost of each pound of jelly beans is $x.
According to question,
For 3 pounds of jelly beans and 2 pounds of trail mix, the total cost is $11.
⇒ → (1)
For 5 pounds of jelly beans and 6 pounds of trail mix, the total cost is $23
⇒ → (2)
Solving (1) and (2), we get
3(1 equation)-(2 equation)=0
⇒
⇒
hence,
⇒
⇒
Putting in
we get ;
