Answer:
Its the upper limit and lower limit of the class
You can solve this easily by using Pascal's Triangle (look that up if need be).
Here are the first four rows of P. Triangle:
1
1 1
1 2 1
1 3 3 1
example: expand (a+b)^3.
Look at the 4th row. Borrow and use those coefficients:
1a^3 + 3 a^2b + 3ab^2 + b^3
Now expand (4x+3y)^3:
1(4x)^3 + 3(4x)^2(3y) + 3(4x)*(3y)^2 + (3y)^3
Look at the 2nd term (above):
3(4x)^2(3y) can be re-written as 144x^2y.
The coeff of the 2nd term is 144. Note that (4)^2 = 16
Minimum payment
= 3% of $1240
= 3/100 x 1340
= $40.20
Answer:
Cereal B.
Step-by-step explanation:
To figure out how much it costs per ounce for each cereal, first we need to divide.
Cereal A: $2.25 / 10 = $.225 per ounce
Cereal B: $3.30 / 15 = $.22 per ounce
So, cereal B is less expensive.
$30 each. Unless that's not the answer you are looking for.
