7.5 is 30 percent of 25 because
25 divided by 10 is 2.5 times 3 is 7.5
Maybe something like:
200s + 105a + 200 = 1,000
You can use x and y instead of s for student and a for adult.
Are the adults and students charged the same? If so then:
200x + 105x + 200 = 1,000
$8 + $7 + $13 + 15 = $43
$x - $43 = $12
x = $55
i am a mathematics teacher. if anything to ask please pm me
-12 would be it because 2 negatives make a positive so -11+23 is -12
