Question

Days: 10, 20, 30, 40
Hay (Ib): 250, 500, 700, 1000
y=25x
At this rate, how much hay will a cow eat over 90 days?

Answer 1

To find out how much hay the cow will eat over 90 days, we need to calculate the hay consumption for each of the given days and then add them up.

Given:
Days: 10, 20, 30, 40
Hay (Ib): 250, 500, 700, 1000

We can apply the equation y = 25x, where y represents the amount of hay consumed (in Ib) and x represents the number of days.

Substituting the values for x:

For day 10: y = 25(10) = 250 Ib
For day 20: y = 25(20) = 500 Ib
For day 30: y = 25(30) = 750 Ib
For day 40: y = 25(40) = 1000 Ib

Now, we need to find the hay consumption for the remaining 50 days (from 40 to 90).

For each day from 41 to 90, the cow will continue to eat 1000 Ib of hay because the equation y = 25x remains the same.

Therefore, the hay consumption for the remaining 50 days is:
50 days * 1000 Ib/day = 50,000 Ib

To find out the total hay consumption over 90 days, we add up the hay consumption from the first 40 days (250 + 500 + 750 + 1000) and the hay consumption from the remaining 50 days (50,000):

Total hay consumption = Hay consumption for the first 40 days + Hay consumption for the remaining 50 days
= 250 + 500 + 750 + 1000 + 50,000
= 52,500 Ib

Therefore, the cow will eat 52,500 Ib of hay over 90 days.
