The table below shows the total cost of buying printer ink cartridges for both members and nonmembers of a shopping club. Price of Ink at Shopping Club Number of ink cartridges purchased Total cost for members (with membership fee) Total cost for nonmembers 0 $30 0 1 $40 $25 2 $50 $50 3 $60 $75 Which statement is supported by the table? The relationship between the number of cartridges purchased and the total cost is proportional for nonmembers but not for members. The relationship between the number of cartridges purchased and the total cost is proportional for members but not for nonmembers. The relationship between the number of cartridges purchased and the total cost is proportional for neither members nor nonmembers.

3.94 x 10⁵ pascals

Explanation:

combined gas law problem

P₁V₁/T₁ =  P₂V₂/T₂ => P₂ = P₁(V₂/V₁)(T₁2T₁)

P₁ = 1 atm at STP       P₂ = unknown

V₁ = 700 ml               V₂ = 200 ml

T₁ = 0°C = 273K        T₂ = 30°C = 303K

P₂ =  1atm(700ml/200ml)(303K/273K) = 3.89 atm

3.89 atm = 3.89 atm(1.01 x 10⁵Pa/atm) = 3.94 x 10⁵ pascals
