First multiply 76 by 80/100
(76 x 80 )/100 = 60.8
Now because the price has to be reduced...
76 - 60.8 = $15.2
Hope this will help.
4.5 x 6.2 = 27.9
Hope that helps
Answer:
Step-by-step explanation:
8 times 6 = 48 (base times high = a rectangle). (A triangle takes half the space)
F. (6*8)/2 =24 square units
B. (2 * 3/2) / 2 = 3/2 = 1.5 square units
G. (4*3)/2 = 6 square units
H. (8/3 *2)/2 = 8/3 = 2.67 square units
The error of percentage is the amount of error over the original amount.
In this case it is 22/95 (not 22 over 77 because 77 is not the original amount they expected to sell.
22/95 = .2315 or 23.2% to the nearest tenth of a percent
Perhaps your teacher just wants 23% as an the approximate error.
