Given parameters:
Quantity of mushroom bought = 4.25pounds
Cost of each mushroom = $2.99
Unknown:
Best estimate for the cost of the mushroom = ?
Solution:
The cost of the mushroom is:
Total cost = quantity of mushroom bought x cost of each mushroom
Total cost = 4.25 x 2.99
You can round 4.25 to 4 and 2.99 to 3

Answer:
59.66
Step-by-step explanation:
Suppose there are n people in this family
one parent is age 40, suppose the rest of the family add up to be y years old
the average is (40+y)/n=20 =>40+y=20n
exclude the 40-year-old parent, the sum of age is still y, the number of family is (n-1), the average is y/(n-1)=15 =>y=15n-15
substitute y=15n-15 in the first equation: 40+(15n-15)=20n
solve for n: 5n=25, n=5
there are a total of 5 people in this family, there are 3 kids.
Answer:
