Mrs. soto bought 8 new monitors and keyboards for the schools computers. the keyboard cost $83. she spent $872 in all. which is a reasonable estimate of how much money mrs. soto paid for each monitor

872-83=789
789/8=98.625

STEP 1:
find total price for keyboards
$83 per keyboard * 8 keyboards= $664 total for keyboards

STEP 2:
find total cost for monitors
Total cost - keyboard cost= monitor $
$872 - $664= $208 total monitor cost

STEP 3:
find price for each monitor
$208 ÷ 8 monitors= $26 per monitor

ANSWER: The price for each monitor is $26. The question says "which" is a reasonable estimate, so if there are choices listed, choose one close to $26.

Hope this helps! :)
