From information given Lisa bought three items.
10 + 20 + 23 = 53 dollars ( which is total pre- tax cost)
The sales tax rate is at 7.2% . Value of this tax in dollars will be:
7.2 % of 53 → (7.2 / 100) × 53 → 0.072 × 53 = 3.816
So the tax rate value is 3.816
Total cost of items will be 53 + 3.816 = 56. 816
Rounded off to the nearest cent 56.816 = 56.80
Therefore Lisa paid a total of $ 56.80
Simplify by combining z terms first.
-10z = 18
Now divide both sides of the equation by -10, and simplify.
z = -9/5
Answer:
Step-by-step explanation:
<h3>Given</h3>
- Price = $79,
- Sales tax = 5%.
<h3>Solution</h3>
Find 5% of $79:
- 79 * 5/100 =
- 395/100 =
- 3.95
a = 4 first term, r = ?, T10 = 100.
Tn = ar^n - 1 formula for g.p
T10 = 4r^ 10 - 1
100 = 4r^9
Divide both side by 4
100/4 = 4/4r^9
25 = r^9 take the 9th root of both side
9√25 = 9√r^9
r = 9√25
To find the nth term
Since Tn = ar^n - 1
Answer:
1. 45 minutes a day cycling
2.$1.55 on each cup of coffee a day
Step-by-step explanation:
1. You would figure up how much he jogs per week by multiplying 15 times 5 which would be 75 minutes and then from there you would subtract 75 from 300 and get 225 and divide 225 and 5 and end up with 45
2. You would multiply $.75 by 4 to figure up how much he spends on donuts which is $3 and then subtract 15.40 from 3 and get 12.40 and divide 12.40 by 8 since he goes twice a day and end up with 1.55
