First, let's define variables:
A = adults
C = children
Okay, now that's done, time to set up the two equations required to solve:
10a + 7c = 6549
a + c = 783
One way you can solve this is to set up the second equation to isolate a variable. For example,
a = -c + 783
Using this, we can plug it into the first equation and solve for c.
10(-c+783) + 7c = 6549
-3c = -1281
c = 427
Now, use the value of 427and plug it in either equation to solve for a.
a + 427 = 783
a = 356
356 adult tickets were sold, and 427 children tickets were sold.

.... Hi don't be mad if you get wrong
So Joan receives 25% commission on the profits of the cars she sells. She got $8,870 on the profit last month. To find the commission, let’s multiply the amount of profit by the percentage. 8,870 * 0.25 is 2,217.5. There. Joan earned $2,217.50 in commission last month.
Answer:
<em>180</em>
Step-by-step explanation:
You need to find 3/8 of 480.
To find a fraction of a number, multiply the fraction by the number.
3/8 of 480 =
= 3/8 * 480
= 3/8 *480/1
= (3 * 480)/(8 * 1)
= 1440/8
= 180
4 is b
6 is d
7 is d
8 is c
9 is a
