Answer:
When they finished, the number of potatoes had Christen peeled is 20 potatoes.
Step-by-step explanation:
Given:
Homer began peeling a pile of 44 potatoes at the rate of 3 potatoes per minute.
Four minutes later, Christen joined him and peeled at the rate of 5 potatoes per minute We have to find the number of potatoes Christen has peeled.
Step 1 of 1
Homer peels 3 potatoes a minute, so in the four minutes he works alone, he peels [tex]$3 \cdot 4=12$[/tex] potatoes.
This leaves 44-12=32 potatoes for them to peel together.
Together, they peel 3+5=8 potatoes per minute, so they need
[tex]$\frac{32 \text { potatoes }}{8 \frac{\text { potatuos }}{\text { minute }}}=4$[/tex]minutes
to peel the rest of the potatoes.
Christen peels 5 potatoes a minute for 4 minutes, so she peels [tex]$5 \cdot 4=20$[/tex] potatoes.
