486.4
Step-by-step explanation:
640 - (24% * 640) =
(1 - 24%) * 640 =
(100% - 24%) * 640 =
76% * 640 =
76 : 100 * 640 =
76 * 640 : 100 =
48,640 : 100 =

486.4
Step-by-step explanation:
Multiply 640 by the percent and then subtract the percent from the whole since the question is asking for a decrease by 24 percent, not what 24 percent of 640 is.
640 * 0.24 = 153.6
640 - 153.6 = 486.4
