Fen completed a triathlon race whose total distance is DDD kilometers. First, she swam a distance of 0.50.50, point, 5 kilometer
Ivanshal [37]

D = 0.5 + 20x + 0.5v

Initial distance covered d1 = 0.5km

If she rode a bicycle for x hours at an average speed of 20 kilometers per hour, then her distance during thus period is,;

Speed = Distance/Time

Distance d2 = speed × time

d2 = 20x

If she ran for 0.5 hour at an average speed of v kilometers per hour, her distance this time will be;

Distance d3 = 0.5v

If her total distance is D, then;

D = d1+d2+d3

D = 0.5 + 20x + 0.5v

Hence an equation that relates D, x, and v is D = 0.5 + 20x + 0.5v

Pauline orders wristbands from two different companies. • Company 1 sells each wristband for $2 and has free shipping. Company 2
MA_775_DIABLO [31]

Answer:

8 wristbands

Step-by-step explanation:

Let us assume that both of the company were ordered to deliver w wristbands.

The amount of money charged by company 1 who sells at $2 and offers free shipping is given as:

2w

The amount of money charged by company 2 who sells at $1.25 and $6 for shipping per order given as:

1.25w + 6

If both companies charge the same amount, hence:

2w = 1.25w + 6

2w - 1.25w = 6

0.75w = 6

w = 6/0.75

w = 8

The two companies charge the same amount for 8 wristbands

Using the 28/36 ratio, determine the maximum allowable recurring debt for someone with a monthly income of $4,850.
lana [24]

Answer:

The correct answer is A. $388

Step-by-step explanation:

The 28/36 Rule states that : A household should spend a maximum of 28% of its gross monthly income on total housing expenses and not more than 36% on total debt service.

Maximum expense on housing expense = 28% of 4850

                                                                    = $1358

Maximum expense on total debt service = 36% of 4850

                                                                    = $1746

Therefore, the maximum allowable recurring debt with a monthly income of $4,850 = 1746 - 1358 = $388

Hence, The option A is correct.
