Ten liters of seawater weigh about 101 newtons. how much would a 1,000-liter tank weigh? how much would a 2,000-liter tank weigh? (hint: how much would 1 liter of seawater weigh? )

Step-by-step explanation:

Given that 10 liters of seawater weigh = 101 Newtons.

We need to find the number of Newtons in 1,000-liter tank and 2,000-liter tank.

10 liters =  101 Newtons.

Dividing both sides by 10, we get

On multiplying both sides by 1000, we get

1 liter × 1000= 1.01 Newtons × 1000.

On multiplying both sides by 2, we get

2× 1000 -liters = 2×1010 Newtons

let x be the money she spent so that she can earn the free t-shirt.

since, she already spent $112.49

⇒

also, as per the statement: jennifer must spend $250 or more in order to qualify for a free t-shirt at the store.

then,

we have an inequality i.,e

subtract 112.49 from both sides we get;

therefore, $137. 51 more money does jennifer need to spend so that she can earn the free t-shirt
