yanalaym [24]

Answer:

The answer to this question can be defined as follows:

Step-by-step explanation:

Given equation:

$\to y + 1 = 12 ( x - 3 )$

Using formula:

$\to \bold{y = mx +c}$

Solving the given equation:

$\to y + 1 = 12 ( x - 3 )\\\\\to y+1 =12x-36\\\\\to y=12x-36-1\\\\\to y= 12x-37\\\\$

compare the value form the given formula:

$\to m= 12$

Correct equation $\to y= 12x-37$

solpe $\to m= 12$

Rico earns a weekly salary of $750 and a 5% total Commission on his sales Sean earns a weekly salary of $1,100 and a 2.5% commis

NNADVOKAT [17]

To answer this item, we let x be the amount of sales for each of them. Their weekly earnings would be as follows,

Rico:
750 + 0.05x

Sean:
1100 + 0.025x

Equating both expressions,

750 + 0.05x = 1100 + 0.025x

Simplifying,
0.025x = 350

The value of x from the equation is 14000.

Answer: $14,000.
