Answer:
The expression for the given discount on item is 74 - [0.4 × 74 + 1.07 × 74]
Step-by-step explanation:
Given as :
The market price of item = m.p = $74
The discount percentage on item = 40%
The sale tax added = 7%
The selling price = s.p = $74 + 7% of $74
I.e s.p = 1.07 × 74
<u>Now, from discount </u>
d % =
Or, 40% =
Or, 0.4 = 1 -
Or, 0.4 × 74 = ( 74 ) - (1.07 × 74)
Or, 74 - (1.07 × 74) - 0.4 × 74 = 0
Or, 74 - 74 (1.07 + 0.4) = 0
Or, 74 - [0.4 × 74 + 1.07 × 74] = 0
Hence, The expression for the given discount on item is 74 - [0.4 × 74 + 1.07 × 74] . Answer
