(8-3)²-(5-2)²
Follow the PEMDAS
P-Parenthesis
E-Exponents
M/D-Multiplication/Division
A/S-Addition/Subtraction
clear the numerals in the parenthesis:
(5)²-(3)²
Now do the exponents:
=25-9
=16
Its just: (5)²-(3)²
Marked up by 135% means
new price=original price+(original price times markup) =125+(125 times 1.35)=293.75
tax
293.75 times 0.075=22.03125
293.75-22.03125=271.718 so aprox $271.72
selling price would be $271.72
Answer:
FALSE
Step-by-step explanation:
If y varies inversely as x., this is expressed as;
y = k/x
k is the proportionality constant
when y = 3 and x = 4
3 = k/4
k = 3 * 4
k = 12
when x = 15;
y = k/x
y =12/15
y = 4/5
Hence y is not equal to 12 when x = 15.
The correct answer is FALSE
