Question

At a bakery, if a costumer purchases fewer than 5 bagels, the cost of each bagel is $1.75. If a customer purchases 5 or more bagels the cost of each bagel is $ 1.25. let b be a function for which b(x) is the cost of purchasing x bagels, where x is a whole number. Which of the following represents an equation for b(x) ?

A: { 1.75x, x < 5
{ 1.25x, x greater than equal to 5

B: { 1.75x, x less than equal to 5
{ 1.25x, x > 5

C: { 1.25x, x < 5
{ 1.75x, x greater than equal to 5

D: { 1.25, x less than equal to five
{ 1.75x, x > 5​

Answer 1

Answer:A: { 1.75x, x < 5

{ 1.25x, x greater than equal to 5

Explanation:

Let x represent the the number of bagels that a costumer purchases

if a costumer purchases fewer than 5 bagels, the cost of each bagel is $1.75. It means that the total cost of the fewer bagels would be 1.75 × x $1.75x.

If a customer purchases 5 or more bagels the cost of each bagel is $ 1.25. It means that the total cost of the bagels would be 1.25 × x $1.25x.

Let b be a function for which b(x) is the cost of purchasing x bagels, where x is a whole number. Then the equation for b(x) would be

A: { 1.75x, x < 5

{ 1.25x, x greater than equal to 5
