Answer:
30% discount
Step-by-step explanation:
To find the percent discount write a proportion.

Cross multiply numerator with denominator of each fraction to solve for x.
1344(100) = 1920(x)
134400 = 1920x
70 = x
This means you pay 70% of the price. The discount was 30%.
Okay, for this one I would use elimination:
8x+(-2y)-10
or
8x-2y=10
2x=4y
x=2y
8(2y)-2y=10
16y-2y=10
14y=10
y=5/7
x=10/7 or 1 3/7. Hope it help!
