A store sells televisions for $360 and video cassette recorders for $270. At the beginning of the week its entire stock is worth

kaheart [24]

Answer:

The number of Television at the beginning was 90

The number of video cassette recorders at the beginning was 89

Step-by-step explanation:

Selling Price of 1 Television =$360.

Selling Price of 1 video cassette recorders for $270.

Let the number of Television at the beginning=x

Let the number of video cassette recorders at the beginning =y

Opening Stock =$56,430.

Therefore:

360x+270y=$56,430.

It sells three quarters of the televisions and one third of the video cassette recorders for a total of $32,310.

$\frac{3}{4}(360)x+\frac{1}{3}(270)y= \$32,310$

270x+90y=32310

We then solve the two equations to obtain x and y.

360x+270y=$56,430. (Multiply by 270)
270x+90y=32310 (Multiply by 360)

97200x+72900y=15236100

97200x+32400y=11631600

Subtract

40500y=3604500

y=89

Substitute y=89 into 270x+90y=32310 to obtain x

270x+90(89)=32310

270x=32310-8010=24300

x=90

Therefore:

The number of Television at the beginning was 90

The number of video cassette recorders at the beginning was 89

[(30 + 6) − 32] ÷ 9 ⋅ 2?

Alex777 [14]

The answer is 0.88889, because:
Order of Operations-
1) Add 30 plus 6 to get 36
2) Subtract 32 from 36 to get 4
3) Divide 4 by 9 to get 0.4444444
4) Multiply 0.4444444 by 2 to get 0.888889
Good luck! <3

Prove that for all integers m and n if m and n are even then m+n is even

In-s [12.5K]

Use either proof by contrapositives or by contradiction:

Proof by contrapositive:

Assume that it is not true that m + n is even. Then either m or n is odd. Since the addition of an odd and an even number is odd, then m + n is odd.

In this case we show that if either m or n is odd then m + n is not even we prove that if m and n are even, m + n must be even

PLEASE HELP IDK THIS!!!

Vadim26 [7]

Hi!

The correct answer is B. The value of M is a product of N and a factor that does not depend on N.

That is true because the relation is : M(t) = N * (1+r)^t , N is N and (1+r)^t is a factor that does not depend on N.

Also, because none of the other answers is true, it makes easier for B to be the one true answer, explanation:

A. The initial value is (1+r) - WRONG, the initial value is N, it says that

C. The function is linear - WRONG, we have exponential growth here, because of the factor (1+r)^t

D. N increases each month - WRONG, N is the initial number of members and it does not change.

Hope this helps!
