Answer:
$405 savings per student every 3 year period.
Step-by-step explanation:
($.75/soda)*(1 soda/day)*(5 school days/week)*(36 weeks/year)*(3 years)
Cancel out the units where possible. You will be left with $ (for the total spent over the 3 years)
.($.75)*(1 )*(5 k)*(36 )*(3 ) = $405 savings per student every 3 year period.
