Real-Life Math -- Solution
As a cattle rancher, you must calculate how many bags of salt and
minerals to take to the pasture for your herds.
You have 853 cows
that each consume 2 ounces (oz.) of salt and 1.5 oz. of minerals each day.
They will be in the pasture for 15 days. Salt and minerals each come in 18-pound
(lb.) bags. (Remember that there are 16 oz. in one pound.)
How many
18-pound bags of salt will you need for the herd for the 15 days?
2
oz. = 0.125 lb (of salt per cow per day)
.125 (pounds of salt)
x 853 (cows) x15 (days) = 1599.375 lb. of salt
1599.375 (pounds
of salt) / 18 (pounds per bag) = 88.854 bags
You will need to take
89 bags of salt to the pasture.
How many 18-pound bags of minerals
will you need for the same time period?
3 (cows) x 0.09375
(pounds of minerals) x 15 (days) = 1199.5312 lb. of minerals
1199.5312
(pounds of minerals) / 18 (pounds per bag) = 66.64 bags
You will
need to take 67 bags of minerals to the pasture.
