Question

I dont know how to solve this , I am not familiar with it and am confused.

Answer 1

a) We have to calculate the total reimbursement.

We can list the types of lunches and reimbursements for each:

0. Free lunches: the school served 29,000 free lulnches and will receive $2.68 for each one.

,

1. Reduced-price lunches: the school served 19,000 reduced-price lunchs and will receiv $2.28 for each one.

,

2. Full price lunches: the school seved 51,000 regular-price lunches and will receive $0.25 for each one.

Then, we can calculate the total reimbursement as:

`\begin{gathered} R=29000\cdot2.68+19000\cdot2.28+51000\cdot0.25 \\ R=77720+43320+12750 \\ R=133790 \end{gathered}`

The lunch reimbursement should be $133,790.

b) The milk reimbursement can be estimated as $0.035 per lunch, so it can be calculated as:

`\begin{gathered} M=(29000+19000+51000)\cdot0.035 \\ M=99000\cdot0.035 \\ M=3465 \end{gathered}`

The milk reinbursement is $3,465.

c) We can calculate the total reinbursement as the sum of the lunch reinbursement and the milk reinbursement:

`R+M=133790+3465=137255`

The total reinbursement is $137,255.

d) We can calculate the average reinbursement per lunch dividing the total reinbursement by the number of lunches:

`(T)/(L)=(137255)/(99000)\approx1.39`

The average reinbursement is $1.39 per lunch.
