The question says she used $\frac{1}{2}$ of it, so she probably used $\frac{1}{2}$ of it. I'm assuming this is an error in the question, and it should be asking how much is left. To solve for that:

$\frac{3}{4}$ - $\frac{1}{2}$

make denominators equal

( $\frac{2}{2}$ × $\frac{3}{4}$ ) - ( $\frac{1}{2}$ × $\frac{4}{4}$ )

$\frac{6}{8}$ - $\frac{4}{8}$

$\frac{2}{8}$

$\frac{1}{4}$

A mail carrier at the U.S. Postal Service works on Sunday delivering high-priority letters and packages. She can deliver 14 ite

Kobotan [32]

Answer:

$4.257

Step-by-step explanation:

Given:

Items delivered per hour = 14

Fixed hourly costs = $47

variable cost = $0.90

Now,

at breakeven point, the profit = 0

Total revenue = total cost

let the charge at breakeven point be 'x'

thus,

x × 14 = $47 + ($0.90 × 14)

x × 14 = $47 + $12.6

14x = $59.6

x = $4.257

Hence, the breakeven charges are $4.257
