Maxis taking a cross-country road trip. Gas prices vary as the friends travel across the US from $4 dollars per gallon on the east coast, to $3 in the mid-US, to $5 on the west coast. a If they used twice as much gas in the mid-US than on either coasts combined, and they spend $515 on gas to purchased 150 gallons of gas, how many gallons of gas did they buy at each price?

you will have $2593.74 in 10 years if you set aside $1,000 at 10%

you will have $9321.91 in 20 years if you set aside $2000 at 8%

you will have $1469.32 in 5 years if you set aside $1000 at 8%

you will have $1296.87 in 10 years if you set aside $500 at 10%

you will have $239.66 in 15 years if you set aside $100 at 6%

you will have $4660.96 in 20 years if you set aside $1000 at 8%

i think the answer is a. science center.

u = 30

continuing your method

= +

subtract from both sides

= - thus

= -

= ⇒ u = 30
