An animal feed producer mixes two types of grain: x and y. each unit of grain x contains 20 grams of fat, 10 grams of protein, and 800 calories, each unit of grain y contains 30 grams of protein, 30 grams of fat, and 600 calories. suppose that the producer wants each unit of the final product to yeild at least 180 grams of fat, 120 grams of protein, and 4,800 calories. if each unit of x costs 180 (pesos) and each unit of y costs 160 (pesos). how many units of each type of grain should the producer use to minimize his cost?

can you rephrase the question ? it is unclear : -)

step-by-step explanation:

15% chance.

step-by-step explanation:

3/10 times, the 5 year old will get a tablet. 5/10 times, the 13 yer old will get a tablet. multiply both fractions to get 15/100 times, both would have a tablet.

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.
