Answer: Yes, you can find the original price of the phone case. The phone case was $560
Step-by-step explanation:
42.00 divided by 25% is $168
$168 divided by 30% is $560
Answer:
for the first equation
f(-3) = 34
f(4) = 6
for the 2nd equation
f(-3) = -56
f(4) ÷ 70
Step-by-step explanation:
my work is attached in a picture.
all you do is substitute each x value into each equation
Answer:
Step-by-step explanation:
<u>Item 1:</u>
Discount = Original price - discount price
= 22.50 - 13.50
= $ 9
Discount percentage = 
= 40%
Discount percentage = 40%
Tax = 14.31 - 13.50 = $0.81
Tax% =
= 6%
Tax percentage = 6%
<u>Item 2:</u>
Tax = 6% of 16.20
= 0.06 * 16.20
= 0.972
Tax = $ 0.97
Total price (including tax )= 16.20 + 0.97 = $ 17.17
x = $ 17.17
<u>Item 3:</u>
Discount = 40% of 32.50
= 0.4 * 32.50
= $ 13
y = 32.50 -13
y = $ 19. 50
Tax = 6% of 19.50
= 0.06 * 19.50
= 1.17
z = 1.17 + 19.50
Z =$ 20.67
Answer:
x = 12
Step-by-step explanation:
Given
p(x) =
x - 3
To find the zero let p(x) = 0, that is
x - 3 = 0 ( add 3 to both sides )
x = 3 ( multiply both sides by 4 )
x = 12 ← zero of p(x)
Answer:
x = 7
Step-by-step explanation:
1*2*3*4*5*6*7 = 5040
x*8*9*10 = 720x
720x = 5040
720 / 5040 = 7
x = 7.
