Question 1049142: I'm having trouble breaking down this word problem.
Problem- A new temperature scale has been introduced called Sandstrum and denoted by S. Here are two comparisons to the Celsius scale. Water freezes at 0 degrees Celsius= -125 degrees S and water boils at 100 degrees Celsius=-50 degrees S.
A.)Find an equation for the line that captures the relationship. Let C be the independent (x) variable. Leave non-whole numbers fractions.
B.) What is the temperature (to the nearest degree in Sandstrum (S) when it is 72 degrees Celsius.

Question 1049004: I want the solution for this question with complete steps. Please help me.
Question: New York city has received a federal grant of $100million for improving public transportation. The funds are to be used only for the purchase of new buses, the purchase of new subway cars, or the repaving of city streets. Costs are estimated at $150,000per bus, $180,000per subway carand $250,000 per mile for the repaving. City officials want to determine different ways of spending the grant money.
a) Define the decision variables and write the equation which ensures complete expenditure of the federal grant.
b) If it has been determined that 100 buses and 200 new subway cars will be purchased, how many miles of city streets can be repaved?
C) If officials wish to spend all of the grant money on one type of improvement, what are the different possibilities?
