Answer:
1360
Step-by-step explanation:
First, you do all the operations inside the parenthesis, and then you multiply the two. Also, remember the order of operations. Multiplication always comes before addition and subtraction.
(2.5x10-8)(9x10-10)
(25 - 8)(90 - 10)
(17)(80) = 17x80 = 1360
The total he earns is the sum of two parts. One part is the $200 per car. The other part is the 3% commission.
total earnings = $200 per car + 3% commission on amount of sales
Let's look at the $200 per car first.
He sold 3 cars.
He earns $200 for each car he sells, so just from that he earns
3 * $200 = $600.
Now we look at the 3% commission.
He earns 3% of the total amount of sales.
The total amount of sales for the 3 cars was $32,343.
He earns 3% of that amount, so his 3% commission is
3% of $32,3243 = 3% * $32,343 = 0.03 * $32,343 = $970.29
The total earnings are the sum of the two parts.
$600 + $970.29 = $1570.29
Let's put these as improper fractions.
30 = 60/2. add the 1/2 to get 61/2
13 = 52/4. add the 3/4 to get 55/4
To add/subtract fractions, they must have the same denominator. (bottom no.)
If we multiply the top and bottom of a fraction by something, it stays equal.
We can conclude that 61/2 = 122/4. (bottom multilpies by 2, so does the top)
Now that we have a common denominator, we can subtract.
The "fourths" just sort of acts like a unit. Subtract 55 from 122 to get
.
We can convert this to an improper fraction simply by dividing 67 by 4.
This leaves us with 16, and a remainder of 3. Our answer is
