find carissa's salary when she sells $1,900 worth of merchandise.

$623

Step-by-step explanation:

Let us suppose that the

Earning = y

Fixed payment = c

Commission paid = m per unit

Case 1.

When 500 units are sold, Earning y = $385

Earning = Fixed Payment + Commission paid per unit * Number of units

385=c+m*500

385=c+500m   ________(a)

Case 2.

When 1000 units are sold  earning y = $470

Earning = c+m*1000

470=c+1000m _________(b)

Subtracting (a) from (b) we get

85=500m

Putting this value of m in (a)

385=c+85

c=300

Hence the fixed payment is $300 and the commission given is $0.17 per unit

Case 3 :

Number of Units sold = 1900

Earning = 300+0.17*1900

Earning = 300+323

Earning = 623

Hence The earning will be $623

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
