1/4 of a mile times 9 equals 9/4 miles in total.
The horses time was 2.5 minutes. 
Her average speed is distance/time.
9/4*1/2.5=9/10

Her average speed was 9/10 of a mile per minute.

Sales Daria sells televisions. She earns a fixed amount for each television and an additional $30 if the buyer gets an extended
alexira [117]

Answer:

$70

Step-by-step explanation:

Daria's total income = fixed income + variable income

Let

Daria's Fixed income = x

additional $30 if the buyer gets an extended warranty

Daria's variable income = 30s

Where,

s = number of televisions with extended warranties she sells

If Daria sells 15 televisions with extended warranties, she earns \$1,500. Find her fixed income

Daria's total income = fixed income + variable income

1500 = x + 30(15)

1500 = x + 450

1500 - 450 = x

1,050 = x

x = $1,050

Daria's total fixed income = $1,050

How much is the fixed amount Daria for each television?

Fixed income per television = Total fixed income / number of television sold

= 1050 / 15

= 70

Fixed income per television = $70
