Answer: $15
Step-by-step explanation:
To find the markup price just multiply 30% by the amount.
30% * 50
0.3 * 50 = 15
B. 16 cm
Square both 20 and 12
20x20=400
12x12=144
400-144=256
find the square root of 256
and the square root is 16
so b is 16 cm
4/5 (20x - 10)...use distributive property...basically multiplying the 4/5 by everything in the parenthesis,
4/5 * 20x - 4/5 * 10 =
16x - 8
