A cake recipe calls for a half cup of butter and two eggs for 12 servings. If you wished to make 30 servings, how much butter would you need? Assume a direct proportion between butter and servings. PLEASE HELP

1 ¼cups

Step-by-step explanation:

12 servings=a half cups

30 servings=? cups

12 servings:30 servings

½cup:? cups

12 servings ÷ ½ = 12×2

=24

30 servings ÷24= 1 ¼cups

30 servings = 1 ¼cups

if i wished to make 30 servings, 1 ¼cups butter would i need.

hope it help

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
