Answer:
The expression is not defined in a set of real numbers.
The square root of a negative number is not defined in the set of real numbers.
32.75 + 39.88 = 72.63
72.63 x 114% = 72.63 x 1.14 = $82.7982 or $82.80 to the nearest cent.
114% is all of the cost of the meal plus 14 % extra for the tip. See how muliplying by 1.14 includes the $72.63 (this saves the step of adding it on at the end if you were only to find 14% of $72.63)
Answer:
The profit is $24
Step-by-step explanation:
Step one:
given the expression for the profit made as

we are told that p is the number of pens, hence for p= 48 by substituting into the expression we can find the profit as
Step two:
Profit= 1.25p-0.75p,
Profit= 1.25(48)-0.75(48),
Profit= 60-36
Profit=24
