The total price with sales tax is $ 246.1
<h3><u>Solution:</u></h3>
Cost of cellphone = $ 210
Cost of battery charger = $ 15
Cost of batteries = $ 5
So total cost can be calculated by adding cost of cellphone and Cost of battery charger and Cost of batteries
Total cost = 210 + 15 + 5 = $ 230
Given that sales tax is 7%
sales tax = 7% of total cost
sales tax = 7 % of 230
Total cost including sales tax = 230 + 16.1 = $ 246.1
Thus the total price with sales tax is $ 246.1
8 times 9 - 7 + 4 times 5
Use PEMDAS. Parentheses, Exponent, Multiply, Divide, Add, Subtract
Multiply:
8 times 9 = 72
4 times 5 = 20
72 - 7 + 20
Add:
72 + 20 = 92
Subtract:
92 - 7 = 85
8 times 9 - 7 + 4 times 5 is equal to 85.
Its 2x^2-4x, to check it add it to 3x^2-2x or
2x^(2)-4x+3x^(2)-2x
Answer:
Step-by-step explanation:
We can write a rational function.
We need to make sure our denominator both have zeroes at 3 and 10.
Set an equation equal to zero to find the function
So we would represent that's as
and
Multiply the two binomial together.
Let our numbetator be any interger.
Use any equation as long as the quadratic is the denominator and the interger is the numerator.
