a total of 10000 was invested in two business ventures A and B .at the of the first year A and B yielded returns of 6% and 23÷4
wolverine [178]

Answer:

(1)

compound amount = 802.5 $

invest earned = 52.5 $

Step-by-step explanation:

total amount = 10000 $

let amount x invested in ventures A and remaining (1000-x) on ventures B

now,

6x/100 +23/400(1000-x ) = 588.75

{24x+23(1000-x)}/400 =588.75

x=235500-230000

x=5500

Amount invested on A = 5500$

Amount invested on B = 4500$

(2)

principle=750$

time= 1 year

effective invest rate = 7%

a) compound amount = p(1+(r/w)^t

=750{1+(7/100)}^1

=802.5$

b) invest earned = 802.5-700 = 52.5$

Help please. Apply the distributive property and simplify, if possible.<br><br> 0.08 (x +6,000)
WARRIOR [948]
By applying the distributive property:
0.08(x+6,000) ---> (0.08)x+(0.08)6,000

By simplifying:
(0.08)x+(0.08)6,000 ---> 0.08x+480

Your answer is 0.08x+480.
