Step 1: Set x to 0

$-2(0) + y = 3$

$y = 3$

(0, 3)

Step 2: Set x to 1

$-2(1) + y = 3$

$-2 + y + 2 = 3 + 2$

$y = 5$

(1, 5)

Step 3: Set x to 2

$-2(2) + y = 3$

$-4 + y + 4 = 3 + 4$

$y = 7$

(2, 7)

Step 4: Set x to 3

$-2(3) + y = 3$

$-6 + y + 6 = 3 + 6$

$y = 9$

Steve and Elizabeth decide to become partners in a children’s cooking school. They need $80,000 for the franchise. They invest i

PilotLPTM [1.2K]

Answer:

The share of Steve is $34,285 .71

The share of Elizabeth is $45,714.28

Step-by-step explanation:

The total investment of Steve and Elizabeth in cooking school = $80, 000

The ratio of investment of Steve and Elizabeth = 3: 4

Let us assume the common factor in the ratio is m.

So, the ratio of Steve = 3 m

and the ratio of Steve = 4 m

So, according to the question:

⇒ 3 m + 4 m = 80,000

or, 7 m = 80,000

⇒ m = 80,000 / 7 = 11,428.57

or, m = 11,428.57

⇒ The share of Steve = 3 m = 3 x (11,428.57) = 34,285 .71

⇒ The share of Elizabeth = 4 m = 4 x (11,428.57) = 45,714.28
