Answer 1
Answer:

Answer:

Both statements (1) and (2) TOGETHER are sufficient to answer the question asked

Step-by-step explanation:

Given statement 1 :

xy < zy < 0,

The product of two numbers are negative if either of the numbers are negative.

∵ if xy < 0 ⇒ Case 1 : x > 0 and y < 0

Case 2 : x < 0 and y > 0,

Thus, Statement is not sufficient to prove y is positive,

Now, Statement 2 :

x < z, x is negative,

That is, x < 0

Combining statements (1) and (2),

We get,

xy < 0, x < 0,

⇒ y > 0

That is, y is positive.

Hence, Both statements (1) and (2) TOGETHER are sufficient to answer the question asked

The sales tax on a new camera is $5.60, which is 8% of the total price.What is the price of the camera?

Answers

$5.60 = 0.08x
Solve by dividing both sides by 0.08
$5.60 ÷ 0.08 = $70
Price: $70
the total price is 6.05 because 8 percent of 5.60 is .45 so 5.60+.45 is 6.05
