Answer:

60

Step-by-step explanation:

If the price is 30% off, you pay 70% of the price

Let x be the original price

.70x = sale price

.70x = 42

Divide each side by .7

.70x/.7 = 42/.7

x =60

The original price is 60

Answer: 38

Step-by-step explanation: to evaluate an expression for these variables, plug in those numbers for the variables.

Plugging in -1 for y and -19 for z gets you this:

-2(-1)^2(-19)

Now simplify according to order of operations (PEMDAS - parenthesis exponents multiplication/division addition/subtraction)

-1^2 = 1

-2(1) = -2

-2(-19) = 38

Your answer is 38
