Question

1. Dina Lopez bought two souvenirs on her recent cruise. One souvenir cost four times the other. If together the souvenirs cost $175, how much did each souvenir cost?

Answer 1

\[175\div5=35\]
souvenir1 = $35, Souvenir 2 = \[4\times$35=$140\]

Answer 2

x=4y
y+x=175 ----> y=175-x
x= 4(175-x) ---> x=700-4x ----> 5x=700 ---> x=140
y=35
