Answer:
Step-by-step explanation:
Answer:
Tax = $0.75
Tip = $2.25
Total (meal + tax + tip)= $18.00
Step-by-step explanation:
When solving for percentages of a number, such as sale tax and tip, multiplying the decimal equivalent of each percentage to the amount will give you the individual costs. For example, in this case the sales tax is 5%, the decimal equivalent of 5% = 5 ÷ 100 = 0.05. To find the amount of tax on Allam's meal, multiply the rate by the amount:
0.05 x $15 = $0.75
Since he plans to leave a 15% tip, we can also multiply the amount of the meal by the planned tip amount:
15 ÷ 100 = 0.15
0.15 x $15 = $2.25
Total amount paid, including tax and tip:
$15 + $0.75 + $2.25 = $18.00
Answer:= 261.905% increase
Solution:
Calculate percentage change
from V1 = 21 to V2 = 76
(V2−V1)|V1|×100
(V2−V1)|V1|×100
=(76−21)|21|×100
=(76−21)|21|×100
=5521×100
=5521×100
=2.61905×100
=2.61905×100
=261.905%change
=261.905%change
=261.905%increase
Answer: x^2-9x+1
Step-by-step explanation:
x^2-7x-7 d(x-1)
(you would just replace x to (x-1)
(x-1)^2-7(x-1)-7
(solve by square rooting (x-1)(x-1) then foil)
x^2-9x+1
