Question

9 Yuki and Roman are photographers for the yearbook. Yuki starts with 20 photos.

She then takes 60 photos each week. Roman starts with 110 photos. He then takes
35 photos each week. After how many weeks will Yuki and Roman have taken the
same number of photos? Write a system of equations that can be used to solve the
problem. Write your answers in the blanks.
P=
W +
p=
W +

Answer 1

I’m sorry, but I don’t really know what P and W stand for, so I’m going to replace them

Yuki
y = 60x + 20
(total = 60 photos a week * x weeks + 20 starting photos)

Roman
y = 35x + 110
(total = 35 photos a week * x weeks + 110 starting photos)

So the system of equations for this problem is:

y = 60x + 20
y = 35x + 110
