Answer:
2.50 + 5B ≤ 21;
Step-by-step explanation:
Cost of eggs = $2.50
Cost of avocado = $5 (bag of 3)
Total budgeted amount = $21
Bags of avocado = B
Therefore :
(Cost of eggs + cost of avocado) ≤ total budgeted amount
($2.50 + $5(B)) ≤ 21
2.50 + 5B ≤ 21
5B ≤ 21 - 2.50
5B ≤ 18.50
B ≤ 18.50 / 5
B ≤ 3.7
Therefore the maximum number of bags can purchase is 3(whole number without exceeding $21)
How many drops per minute?
There are 16 drops per ML.
1000 ML = 1 L.
1L = 1000 ML
Therefore 1.08 L = 1.08 * 1000 = 1080 ML
16 drops per ML means I ML has 16 drops.
Therefore 1080 ML has: (1080 * 16) drops.
Number of drops per min:
Since the entire process took 3 hours = 3 * 60 minutes = 180 minutes.
Therefore Number of drops per minute = Number of Drops / Time in minutes
= (1080 * 16) /(180)
= 96 drops per minute.

Step-by-step explanation:
Answer: There were 78 red apples at the party.
Step-by-step explanation:
This situation can be represented by the equation
x + 3x + 2(3x) = 130 where x is the number of green apples, 3x is the number of yellow apples and 2(3x) is the number of red apples.
Now solve for x
x +3x +2(3x) =130
4x + 6x = 130
10x = 130
x = 13
Now we know that x is 13 so put it into the expression for red apples and solve for the actual number of red apples.
2 * (3*13) = ?
2 * 39 = 78
