A manufacturer produces two models of toy airplanes. It takes the manufacturer 25 minutes to assemble model A and 15 minutes to package it. It takes the manufacturer 15 minutes to assemble model B and 5 minutes to package it. In a given week, the total available time for assembling is 2400 minutes, and the total available time for packaging is 1200 minutes. Model A earns a profit of $12 for each unit sold and model B earns a profit of $5 for each unit sold. Assuming the manufacturer is able to sell as many models as it makes, how many units of each model should be produced to maximize the profit for the given week?

i believe the answer is d.

hope it you! : d

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
