richard klein works as auto mechanic and earns the following commission rates 3.00 percent for oil changes 5.00 percent for tune ups and 6.25 percent on auto parts sales he is guaranteed a minimum salary of $2,450.00 per month last month he brought in $2,500.00 in oil changes $4,500.00 in tune ups and sold $28,200.00 in parts what is his gross pay for the month

Richard Klein Gross pay for the month=$4,512.50

Step-by-step explanation:

Richard Klein guaranteed minimum salary per month = $2,450.00

Commission for oil changes =3% x $2,500.00 = $75

Commission for tune ups  =5% x $4,500.00=$225

Commission for auto part sales   =6.25% x $28,200.00  =$1,762.5

Richard Klein Gross pay for the month=guaranteed minimum salary per month + his commissions on oil changes, tune ups and auto part sales

= $2,450.00 $75+ $225+  $1,762.5   =   $4,512.50

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
