Question

The USDA pays schools for each lunch served. As of the 2014–15 school year, it paid $2.98 for each free lunch,

$2.58 for each reduced-price lunch, and $0.28 for each full-price lunch.
If f = the number of free lunches served, r = the number of reduced-price lunches served, and p = the number of
full-price lunches served, write an algebraic expression that shows the total amount each school receives in
per-meal reimbursements.

Answer 1

$32.80

Explanation:

For this case we have that the total daily protein consumption is given by:

Now, we find the percentage corresponding to breakfast:

53g ---------> 100%

17g -----------> x

Where "x" represents the percentage of protein equivalent to breakfast:

Thus, at breakfast approximately 32.08% of the total protein should be consumed.
