Los gerentes de un almacén quieren enviar códigos de descuento de $150 en la compra de $750 a quienes se han suscrito a su lista de correo electrónico. El código de descuento tendrá tres letras, seguidas de un dígito, seguido de una letra. Las letras P, Q, R y Ñ no se usarán. Así que se usarán 23 letras y 10 dígitos. Suponer que las letras se pueden repetir. ¿Cuántos códigos de descuento se pueden crear de esta manera?

Given the following linear function sketch the graph of the function and find the domain and range. ƒ(x) = -5x + 4

Edger needs 6 cookies and 2 brownies for every 4 plates how many cookies and brownies does he need for 10 plates

Acaterer knows he will need 60, 50, 80, 40 and 50 dinner napkins on five successive evenings. he can purchase new napkins initially at 25 cents each, after which he can have dirty napkins laundered by a fast one-day laundry service (i. e., dirty napkins given at the end of the day will be ready for use the following day) at 15 cents each, or by a slow two-day service at 8 cents each or both. the caterer wants to know how many napkins he should purchase initially and how many dirty napkins should be laundered by fast and slow service on each of the days in order to minimize his total costs. formulate the caterer’s problem as a linear program as follows (you must state any assumptions you make): a. define all variables clearly. how many are there? b. write out the constraints that must be satisfied, briefly explaining each. (do not simplify.) write out the objective function to be minimized. (do not simplify.)
