Step-by-step explanation:
159.39(1-25/100)
159.39(100-25)/100
159.39(75)/100
159.39(0.75)
$119.54
Because the design is scaled by 3, the new dimensions are 9*3 X 12*3 = 27 X 36
Since the dimensions are 27 X 36, the area is equal to 27*36 = 972 square inches.
Answer:
50% of $6
$3
$9
Step-by-step explanation:
We are given,
The original price for the ticket = $6
Also, the prices of the tickets were raised by 50%.
Thus, the raise in the prices of tickets = 50% of $6.
i.e. Raise = 50% × 6 = 0.5 × 6 = $3
Since, the raise in the prices is by $3.
Thus, the new price of the tickets = $6 + $3 = $9.
Hence, the percent equation is 50% of $6, the amount by which ticket prices rose is $3 and the new amount is $9.
