Answer:
a. $5.43
b. $141.25
c. $8.75
Step-by-step explanation:
First you find the total amount you it cost for all the items
$135.82 + 4% = $141.25
You give three $50 dollar bills
50 * 3 = 150
$150 is the amount you give
--------------------------------------
141.25 - 135.82 = 5.43
$5.43 is the amount of the sale price
---------------------------------------
To find the amount is cost for all the items you add the sales tax + the original price
$135.82 + 4% = $141.25
$141.25 is the amount including the tax
---------------------------------------
Subtract
150 - 141.25 = 8.75
So you will get $8.75 back
-3(x-1)/x would be your answer
Answer:
y = 3^(x + 1).
Step-by-step explanation:
Here the y values are increasing by a factor 3 and when x = 0 y = 3,
so y = (3)^1 when x = 0 - that is y = (3)^(0 + 1) = 3.
So y = 3^(x + 1) is the rule.
Check: when x = -2, y = 3^(-2+1) = 3 ^-1 = 1/3.
When x = 1, y = 3(1+1) = 3^2 = 9.
Answer:
it's 3
Step-by-step explanation:
it went up 7 floors and went down 4 floors, if you subtracted those it will be 3.
-2 because I’m just going to guess because I can’t see the system of equations
