Answer:

x = 150 miles

Cost = $100

Step-by-step explanation:

Company A = 50 + 20 + 0.20x

= 70 + 0.20x

Company B = 55 + 0.30x

Where,

x =number of miles

find the number of miles for which the companies charge will be the same

Equate the charges of both companies

70 + 0.20x = 55 + 0.30x

70 - 55 = 0.30x - 0.20x

15 = 0.10x

Divide both sides by 0.10

x = 15 / 0.10

= 150

x = 150 miles

The number of miles for which the companies charge will be the same is 150 miles

Substitute 150 miles into any of the companies charges to find the charge

Company B = 55 + 0.30x

= 55 + 0.30(150)

= 55 + 45

= $100

Bottles of sparkling water usually cost $1.69 each. This week they are in sale for 4 for $5. You bought one last week and one th
Phantasy [73]

Answer:

The cost of 1 sparkling bottle in this week is less than last week, so we pay less this week.

We pay $0.44 less this week.

Step-by-step explanation:

Given,

Cost of 1 sparkling bottle last week = $1.69

This week cost of 4 bottles is $5.

So we have to find the cost of 1 bottle.

For this we use the unitary method, we get the cost of 1 bottle;

Cost of 1 sparkling bottle this week = \frac{5}{4}=\$1.25

The cost of 1 sparkling bottle in this week is less than last week, so we pay less this week.

For finding how much we pay less this week, we have to subtract cost of 1 sparkling bottle this week from cost of 1 sparkling bottle last week.

Framing the above sentence in equation form, we get;

Amount\ of\ money\ we\ pay\ less=1.69-1.25=\$0.44

Hence we pay $0.44 less this week.

The relation between pressure and volume is given as
v = 18000/p
where
v = volume, in³
p = pressure, lb/in²

When the pressure is p = 900 lb/in², then the volume is
v = 18000/900 = 20 in³

Answer: 20 in³
