If it is 60% off, then u r actually paying 40%
so ur paying 40% of 320....turn ur percent to a decimal..." of " means multiply
so the sale price is : 0.40(320) = $ 128 <==

320 - 0.60(320) = 320 - 192 = $ 128 <==
Answer:
2/3
Step-by-step explanation:
The work done on the box is ...
Fd = (60 N)(10 m) = 600 N·m = 600 J
The amount of energy the box has as a result is ...
KE = 1/2mv² = (1/2)(8 kg)(10 m/s)² = 400 kg·m²/s² = 400 J
The ratio of box energy to energy input is ...
η = (400 J)/(600 J) = 2/3 . . . ≈ 66.7%
