Let a, b, c,...x, y, z be variables such that:
- Every consonant that is preceded by a vowel is two less than twice the value of that vowel.
- Every consonant that is preceded by another consonant is twice the value of that consonant.
- Every vowel is one sixteenth the value of the consonant preceding it.
Write z in terms of a.
Find the sum of x, y, z, and w if
3x + y = 170
y + 3z = 50
z + x - 2w = 30
This year Mr. Krank spent three times as much money on gifts for family members as he did on gifts for co-workers. The amount of money he spent on Christmas decorations was $150 less than the amount of money he spent on Christmas cards. The amount he spent on Christmas charities exceeded the combination of co-worker gifts and Christmas card expense by 20%. In addition to all of this, a third of the total spent on Christmas was expenses related to their famous Christmas-Eve party. If the Kranks had not purchased any Christmas gifts, they would have spent $1983 on Christmas. If, instead, they had chosen to give gifts but skip the Christmas cards, they would have spent $2673 in all.
If the Kranks skipped Christmas altogether, how much money would they have saved?

Each of five children blow some bubbles. The number of bubbles blown by the first child equals the number of bubbles blown by the second and third children combined. The number of bubbles blown by the second child is ten less than the number of bubbles blown by the third and fourth children combined. The number of bubbles blown by the third child is the number of bubbles blown by the fifth child, minus the number of bubbles blown by the fourth child. If the fifth child blew 32 bubbles, how many bubbles were blown by the first and fourth children combined?
