Answer:
$8.2
Step-by-step explanation:
The final price of the coat = $45 -0.2 * $45 = $36
The final price of the suit = $95 − 0.3 * $95 = $66.5
sarosh's commission = 0.08 * ( $36 + $66 ) = $8.2
Answer:
20 and 40
Step-by-step explanation:
120/2=60
3x=60
x=20
20x2=40 since it is two times
X = 25 dollar items and y = 15 dollar items
x + y = 72....x = 72 - y
25x + 15y = 1380
25(72 - y) + 15y = 1380
1800 - 25y + 15y = 1380
-25y + 15y = 1380 - 1800
-10y = - 420
y = -420/-10
y = 42
x + y = 72
x + 42 = 72
x = 72 - 42
x = 30
so they sold 30 twenty five dollar items (x) and 42 fifteen dollar items (y)
It's true and the equation is
