Answer:
c = 29.5 or
c = 59/2
Step-by-step explanation:
2 (4 + c) = 67
8 + 2c = 67
8 - 8 + 2c = 67 - 8
2c = 59
c = 29.5
If you mean like a method to solve it fast here I have 1 solution I usually use;
3x2.7
3x.7=2.1
3x2=6
Then in the question there is 1 number behind the decimal point so the answer should have 1 number behind as well.
=8.1
The properties of integer exponents can be used to write equivalent expressions by combining numeric or algebraic expressions that have a common base, distributing exponents to products and quotients, and simplifying powers of powers.
20(1-p)
20(1-0.25)
20(0.75)
=15
so the sale price is $15
hope this helps !
