Answer:
12 chocolates
Step-by-step explanation:
Represent the original number of chocolates by c.
Then (1/4)(2/3)c = 2
Solving this for c, we multiply both sides by 4: (2/3)c = 8
and then multiply both sides by (3/2): c = (3/2)(8) = 12
Originally the box contained 12 chocolates.
Answer:
(2A /h) - b1 = b2
Step-by-step explanation:
A = 1/2 h ( b1 + b2)
Multiply each side by 2
2A = 2*1/2 h ( b1 + b2)
2A = h ( b1 + b2)
Divide each side by h
2A/h= h/h ( b1 + b2)
2A/h= b1 + b2
Subtract b1 from each side
2A /h - b1 = b2
Answer is $330.63 because 15% of 287.5 is 43.125 then you add 47.125 to 287.5 and get 330.63
Step-by-step explanation:
