1 - 3) for question 1 to 3. you can answer by looking into table.
4. in this question. it is now asking for the 3months or the 90th days but it does not reflect on the table because it ends only on 80 days. by examining the table, you can see the pattern of how much rice increase every 10 days which is 1/2. if the 80th days, they need 4 sacks. meaning on the 90th days they need 4 1/2 sacks.
Other way of solving this is by using the linear equation stated in the problem
that y = 1 / 20 (x), where y is the sacks and x is the days. by substituting the x = 90
y = 90 /20 = 4.5 or 4 1/2 sacks.
5.) if the rice price per sacks = Php 2,500.00, therefore the the money needed to stock up for 3months:
