Answer: 7 gallons; 14 gallons
Step-by-step explanation:
Let the amount of water in the first container be x.
Since one container holds 2 times as much as the other, the second container will be: = x × 2 = 2x
The total amount of water is 21 gallons. This means:
x + 2x = 21
3x = 21
x = 7 gallons
First container = 7 gallons
Second container= 2x = 2×7 = 14 gallons
Part A
Total number of litres in the punch = grape juice + lemon lime soda
let grape juice be
, and lemon-lime soda be
the expression for the total number of litres in the punch is given by
We know the number of litres for the lemon-lime soda, hence the expression is
Part B:
40% of the punch is lemon-lime soda which is 2 litres
That means every 1 litre represents 20% of the punch
60% of the punch is grape-juice, hence 60÷20 = 3 litres of grape juice
Just add two zeros to the front to make it kg .00123

Answer:
- 3 packages of American (7/8 lb)
- 2 packages of cheddar (1/2 lb)
Step-by-step explanation:
The amount of cheese Mrs Mack needs is an odd number of eighths of a pound. So, she must buy an odd number of the 7/8 pound packages.
If she were to buy any 1/5 pound packages, she would have to buy a multiple of 5 of them so as to have an integral number of eighths. The only suitable multiple is 0.
If Mrs Mack buys 1 of the 7/8 pound packages, she cannot make up the difference with half-pound packages. She must buy 3 of the 7/8 pound packages, for a total of 2 5/8 pounds of American cheese. The remaining pound can be bought as 2 of the 1/2 pound packages.
To buy 3 5/8 pounds, Mrs Mack must purchase ...
3 packages of American cheese (7/8 lb each)
2 packages of Cheddar cheese (1/2 lb each)
