First we calculate the number of moles of sugar (which I assume is sucrose). number of moles = mass / molecular weight number of moles of sugar = 19 / 342 = 0.055 moles Now we may calculate the molarity of the solution. molarity = number of moles / solution volume (L) molarity = 0.055 / 0.05 = 1.1 M

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
