# Urgent d1 exam question help! Watch

1. A charity produces mixed packs of posters and flyers to send out to sponsors. Pack A contains 40 posters and 20 flyers.
Pack B contains 30 posters and 50 flyers.
The charity must send out at least 15000 flyers.
The charity wants between 40% and 60% of the total packs produced to be Pack As.
Posters cost 15p each and flyers cost 3p each.
The charity wishes to minimise its costs.
Let x represent the number of Pack As produced, and y represent the number of Pack Bs produced.

Formulate this as a linear programming problem, stating the objective and listing the constraints as
simplified inequalities with integer coefficients.
You should not attempt to solve the problem
