11.50-3.00=8.50
some of the pieces of pottery were sold at 11.50 and some of the pieces of pottery were sold at 8.50.
let x = number of pieces of pottery sold at 11.50.
let y = number of pieces of pottery sold at 8.50.
since a total of 99 pieces of pottery were sold, and since the total revenue collected was 931.50, you get the following equations.
x + y = 99
11.50 * x + 8.50 * y = 931.50
the first equation says that the total number of pieces of pottery sold was 99.
the second equation says that the total money collected was 931.50, when x were sold at 11.50 and y were sold at 8.50.
these two equations need to be solved simultaneously.
we'll solve by elimination.
multiply both sides of the first equation by 11.50 and leave the second equation as is to get:
11.5 * x + 11.5 * y = 1138.5
11.5 * x + 8.50 * y = 931.5
subtract the second equation from the first to get:
3.00 * y = 207
divide both sides of that equation by 3 to get y = 69.
since x + y = 99, this means that x has to be equal to 30.
your solution is that x = 30 and y = 69.
this means that the number of pieces of pottery sold at 11.50 is 30 and the number of pieces of pottery sold at 8.50 is 69.
30 * 11.50 + 69 * 8.50 is equal to 931.50.
solution looks good.
they sold 30 at the original price and 69 at the reduced price.
Offers are parallel because they would never intersect
Using the information given we can set up a simple math equation.
(1.6 x 4) + 0.8 + (0.3 × 2) = Paint used
6.4 + 0.8 + 0.6 = Paint used
7.8 = Paint used.
Finally you end up with your answe being B. 7.8 gallons of paint used.
Step-by-step explanation:
First of all, we need to Reduce or Simplify the fractions to do this problem.
18/56 simplified is 9/28.
12/56 simplified is 3/14.
So our equation now is 9/24 divided by 3/14. (You do not need common denominators for dividing fractions.)
To find the answer of this problem, we follow a formula, Keep, Change, Flip.
You keep it the same.
Change the division sign to multiplication sign.
Then Flip the second fraction's numerator and denominator.
For example: 3/8, flipped is 8/3.
For example: 14/6, flipped is 6/14.
So we keep the problem the same:
9/28 / 3/14.
Change the division sign to multiplication sign:
9/28 x 3/14.
Then Flip the second fraction:
9/28 x 14/3 = ?
9 x 14 = 126,
28 x 3 =84.
Our answer is 126/84.
We should reduce our answer to get the proper results.
Reduced is:
3/2
Our final answer is 3/2.
Good luck on testing!
