customer gives you a coupon for 15% off his entire
order. The order total was $12.33. Find the discount
amount. Find the new total cost with a 4.5% tax.
First you need to find the discount amount. You do this by changing 15% into a decimal.
So,
15/100 = 0.15
Then we multiply,
0.15x12.33 = 1.8495 Or $1.85
Since there was a 15% discount, we have to subtract 12.33 by 1.85.
So,
12.33-1.85 = 10.48
If there is a 4.5% tax, we'll change 4.5% into a decimal.
So,
4.5/100 = 0.045
Then we multiply by the new amount,
0.045x10.48 = 0.4716
Now we have to add because it is a 4.5% tax.
So,
10.48+0.4716 = $10.95
Therefore, the new total cost was $10.95.

The sum of the two numbers is 97. The difference is 45. What is the two numbers?
Answer:
71 and 26 are the two numbers. They add to 97 and have a difference of 45.
Answer:
x = 71
y = 26
Step-by-step explanation:
x + y = 97
x - y = 45
if you add the two equations together then the y-values will drop out and you will have:
2x = 142
x = 71
if we know 'x' we can now find 'y':
71 - y = 45
-y = -26, therefore y = 26

simplify expressions 2y(y+3)+4y(y-1)
Answer:
6y² + 2y
Step-by-step explanation:
Use distributive property:a*(b+c) =a*b + a*c
2y(y + 3) + 4y(y -1) =2y*y + 2y*3 + 4y*y - 4y*1
= 2y² + 6y + 4y² - 4y
= 2y² + 4y² + 6y - 4y {Combine like terms}
= 6y² + 2y
