Using proportions, it is found that the deadline for the project is of April 17th.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
The number of days they need is:
45 + 20 + 15 + 10 = 90.
The number of weeks they need, considering 6-day weeks, is:
90/6 = 15.
Looking at a calendar, we have that:
- 4 weeks after January 2nd is January 30th.
- 8 weeks after January 2nd is February 27th.
- 12 weeks after January 2nd is March 27th.
- 13 weeks after January 2nd is April 3rd.
- 15 weeks after January 2nd is April 17th.
The deadline for the project is of April 17th.
