Brooke Hicks · Answer 1

300 + 0.05x = 800

0.05x = 800 - 300

0.05x = 500

x = 500/0.05

x = 10,000

check ...

300 + 0.05 (10,000) = 800

300 + 500 = 800

800 = 800 (correct)

there must be $10,000 sold to make $800 for the week

Shaniya · Answer 2

300 + 0.05x = 800

0.05x = 800 - 300

0.05x = 500

x = 500/0.05

x = 10,000

check ...

300 + 0.05 (10,000) = 800

300 + 500 = 800

800 = 800 (correct)

there must be $10,000 sold to make $800 for the week
