<span>To find the percent increase get the difference of the two numbers 13.5 - 12.50 = 1
Then divide the difference by the original amount 12.50 = 1/12.50 = .08 Next turn .08 into a percent by multiplying .08 by 100 .08 x 100= 8 = 8 % increase

Answer:
-3/5
Step-by-step explanation:
Consider the slope-intercept form, y=mx+b, where m= the slope, and b= the y-intercept. Here, 4 is b and -2 is m. Therefore, the slope is -2.
Answer:
No, a polygon cannot have a decimal number of sides.
Explanation:
- exterior angle of a polygon = 360 ÷ number of sides
using the formula:
14 = 360 ÷ number of sides
1/number of sides = 14/360
number of sides = 360/14
number of sides = 25.71428571
Answer:
Adult ticket is $7.5 while a child's ticket is $11
Step-by-step explanation:
Given data
Let the cost of an adult ticket be x
and the cost of a child ticket be y
The Seward family
2x+3y= 44.50---------1
The Sena family
3x+6y= 78-------------2
solve 1 and 2
2x+3y= 44.50 X2
3x+6y= 78 X1
4x+6y= 89
- 3x+6y= 78
x+ 0= 11
x= 11
put x= 11 in 1
2x+3y= 44.50
2*11+3y= 44.5
22+3y=44.5
3y= 44.5-22
3y= 22.5
y= 22.5/3
y= 7.5
Hence Adult ticket is $7.5 while a child's ticket is $11
