(a) let ( a ) be the unknown amount kira would charge (in dollars). using the values below, create a proportion that can be used to find ( a ).
values: ( a ) ( 240 ) ( 18 ) ( 3 )
( \frac{square}{square} = \frac{square}{square} )

Explanation:

$\frac{A}{3} = \frac{240}{18}$

Step2: Solve for A

$A = \frac{240 \times 3}{18}$

Step3: Simplify calculation

$A = \frac{720}{18} = 40$

Answer:

Part (a) Proportion:

$\frac{A}{3} = \frac{240}{18}$ (or equivalent $\frac{A}{240} = \frac{3}{18}$)
