Answer:
$1023.74
Step-by-step explanation:
Joan wants to buy a new TV that costs $1299.99. The store has a discount on the TV for 30% off. The city Joan lives in has a 12.5% sales tax. What will be the total cost of the TV?
Step 1
We find the new price after the discount.
Discount = % Discount × Current price
= 30% × $1299.99
= $389.997
The new discounted price =
$1299.99 - $389.997
= $909.993
Step 2
We calculate the Sales tax
The city Joan lives in has a 12.5% sales tax.
Hence,
The sales tax =
12.5% × $909.993
= 12.5/100 × $909.993
= $113.749125
Step 3
The total cost of the TV is calculated as:
Sales Tax + Discounted price
= $113.749125 + $909.993
= $1023.742125
Approximately = $1023.74
The total cost of the TV = $1023.74

Answer:
In Grade 8, 17% of students liked running
Step-by-step explanation:
Although this table is incomplete, there are still enough information to answer.
First, we need to be aware that the data here is written in decimal numbers, which is another way to write percentages.
In other words, 100% equals to 1, which is to say that if we multiply decimal number with 100 we'll get the percentage:
0.39 = 39%
0.04 = 4%
Another important thing to establish is that the value of decimal number DOES NOT mean the number of people, it only suggests the ratio:
0.26 does not mean 26 people etc.
Knowing this, from this incomplete table, we see that 0.17 students from grade 8 liked running. And now we know that 0.17 equals to 17%, which makes B the correct answer.
