Jerry receives a 15% employee discount at
the store where he works, If he pays $151.30
for an item, what was the original price of the
item?

hi

if he pays  15 % less, then. he pays  1- 0,15 = 0,85 of full price.

Let's call  X full price

then. o,85 X. = 151.30

                  X = 151.3. / 0,85

                  X =  178

$178

Step-by-step explanation:

Let's say the original price is x. If there's a 15% discount on x, we have the expression:

x - 15% * x

We know that the discounted price is $151.30, so set this equal:

x - 15% * x = 151.30

x * ( 1 - 15%) = 151.30

Remember that % just means "out of 100", so 15% = 15/100:

x * (1 - 15/100) = 151.30

x * (1 - 0.15) = 151.30

x * 0.85 = 151.30

x = 151.30 / 0.85 = 178

The original price was thus $178.

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

the factor is 2

step-by-step explanation:

let f(x)=8(3^(x−2)+2)

to stretch a graph by 3, it would be 3f(x)

g(x) =3f(x)

g(x) = 3*(8(3^(x−2))+2)

g(x) = 24 (3^(x-2) )+6

x     −2     0     2     4     6

f(x) 1/64 1/16   1/4     1     4

1/64 * z * z = 1/16

i multiplies by z twice because it its 2 steps from -2 to 0

1/64 z^2 = 1/16

multiply by 64 to clear the fraction on the left side

1/4 * 64 z^2 =1/16 *64

z^2 = 4

take the square root of each side

sqrt(z^2) = ±sqrt(4)

z = ±2  

we are multiplying by 2 each time.
