1.) The monthly costs associated with driving a Ford Explorer are the monthly loan payment plus the cost of filling up ur tank with gasoline. If you fill up 3 times a month your total money cost is $520. If you fill up 5 times a month, your total monthly cost is $600. How much is your monthly loan and how much does it cost everytime you fill up with gasoline?

2. A clothing store sells a shirt costing $20 for $33 and a jacket costing $60 for $93. If the markup policy of the store for items costing over $10 is assumed to be linear, write an equation that expresses retail price R in terms of cost C (wholesale price) What does the store pay for a suit that retails for $240.

10 pts to the best answer. please show me how i got 173 and 1/3 = x + b for one equation for the first ? and 120 =x + b for another equation to #1. and my equation to the second one is y = 3/4 X + 6 and 1/3. Am I going in the right direction.

The following equation is for the next question.
t½ = τ ln2 = RC ln2

--------------------------------------------------------------------------------
2. Given a resistance of 101 Ohms and a capacitance of 190micro Farads,
what is t½?
t½ = ______________seconds.
(Hint: There are 106 micro Farads in one Farad. So the capacitance is 0.00019 Farads.
(Answer with three significant figures (in seconds) or N/A if there is no answer.)

A silo has a cylindrical main section and a hemispherical roof. If the height of the main sectio is 10m, what should the radius be in order that the volume of the silo(including the part inside the roof section) is 2000 m cube.?

2. The height, length, and width of a small box are consecutive integers with the height being the smallest of the three dimensions. If the length and width are increased by 1 cm each and the height is doubled, then the volume is increased by 120cm cube. Find the dimensions of the original small box.
