Sales Application Jamal is a door to door vacuum salesman. His weekly salary, S, is $250 plus $50 for each
vacuum he sells. This can be written as S= 250 + 50v, where v is the number of
vacuums sold. If Jamal earns $1800 for a week's work, how many vacuums did he sell?
If Jamal earns $1800 for a week's work, how many vacuums did he sell?

31

Step-by-step explanation:

3 times the same question ?

but yes, the formula for Jamal's salary is

S = 250 + 50v

now we know for that week that S = 1800

so, now we solve for v :

1800 = 250 + 50v

1550 = 50v

155 = 5v

v = 31

so, Jamal sold 31 vacuums in that week.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
