Answer:
- s + m + L = 78
- 0.45s +0.60m +0.75L = 46.95
- s - m + L = 4
Step-by-step explanation:
The problem statement asks for the number of each size cup sold. You are told there are three sizes, so it is convenient to use one variable to represent the number of cups of a given size that were sold—three variables total.The problem statements tell you the relationships between the numbers:
- the total number of cups sold
- the total value of cups sold
- the relationship between numbers of one size versus other sizes
It is appropriate to write an equation for each of these relationships, for a total of three equations. (Here, the last of these equations is put into standard form to make it easier to translate this to a matrix equation for solving by calculator.)
___
The solution is: 20 small, 37 medium, and 21 large.
The ration is 3:1 because Kaleel made 3 TIMES as many baskets as John.
66 yards is greater, because in the metric system 1 yard= 3 feet. 66 yards is equal to 198 feet. Therefore, making 66 feet greater than 180 feet.
Answer: Option 'B' is correct.
Step-by-step explanation:
Number of pounds of candy = 30
Cost per pound = $1.10
Total amount would be
Let the number of pound that sold at $1.50 per pound be 'x'.
Let the number of pound that sold at 90 cents per pound be '30-x.
According to question, we get that
Hence, there are 10 pounds of chocolates worth $1.50 per pound.
Therefore, Option 'B' is correct.
