I don’t understand the concept of this problem

Mathematics
1 answer:
maxonik [38]3 years ago
5 0

Answer:

This uses the method of elimination/addition.

Step-by-step explanation:

1 (9x + 7y = 15)

-7 (5x + y = -9) <— let’s eliminate y for both equations

9x + 7y = 15

+ -35x - 7y = 63 <— add both of the equations

—————————————————

- 26x + 0y = 6

(Please let me know if the answer is correct or not)

you deposit $1.000 in a saving account that earns 0.5% each month. Assuming you do not deposit or withdraw any from the account,
Mumz [18]

1 + {[(1 * 0.5) x 12] x 3}

1 + {[0.5 x 12] x 3}

1 + {6 x 3}

1 + 18

19

I'm not sure if that's a 1.000 or 1,000 so:

1,000 + {[(1,000 * .5) x 12] x 3}

1,000 + {[500 x 12] x 3}

1,000 + {6,000 x 3}

1,000 + 18,000

19,000

Gabe Industries sells two​ products, Basic models and Deluxe models. Basic models sell for​ $41 per unit with variable costs of​
Hitman42 [59]

Answer:

b. 63 units

Step-by-step explanation:

The breakeven point occurs when the revenue is equal to the expenses. It means that the profit is 0. So, for the Basic model, the revenue is the sell less the costs: $41 - $15 = $26.For the Deluxe model, the revenue per unit is 0 ($45 - $45).

So, calling x the Basic model units, ad y the Deluxe model units, the total revenue will be: 26x, which must be equal to the expenses = $1,310.40:

26x = 1310.40

x = 50.4 units

y = x/4, because for 1 Deluxe model four Basic models are selled.

y = 50.4/4 = 12.6 units

The total units for breakeven point is 50.4 + 12.6 = 63 units.
