It is 7.70 that is what I got
Hey there! I'm happy to help!
We see that if you add 5% to the original cost, we have $168 as our cost. This means that 105% of the original cost is 168. Let's set up an equation to find the original cost. Let's call our original cost c.
To turn a percent into a decimal, you divide by 100.
1.05c=168
We divide both sides by 1.05.
c=160
Therefore, the original cost was $160.
Have a wonderful day! :D
Answer:
Let x = the number
A negative number is 42 less than its square ⇒
x = x2 - 42
x2 - x - 42 = 0
(x - 7)(x + 6) = 0
x = 7 or -6
But since it is given that x is negative, the final answer is x = -6.
