Answer:
The piecewise function is given as follows;
Step-by-step explanation:
The given parameters are;
The cost of each bag of snickers = $3.45
The cost of each bag of sneakers when buying 4 or more bags = $3.00
Let "n" be the number of bags of snickers and "C(n)" be the cost of all the snickers purchased
The piecewise function is C(n) = {($3.45 × n) for n < 3
{($3.00 × n) for n ≥ 4
when you raise an exponent to a power you multiply
Also since the terms inside the parenthesis are multiplied and not added, you don't have to worry about expanding it
it's easy..here have a look at it.
280
350÷5 will give you quarters. 350÷50=70. 70x4=280
