While in europe, if you drive 123 km per day, how much money would you spend on gas in one week if gas costs 1.10 euros per liter and your car's gas mileage is 31.0 mi/gal ? assume that 1euro=1.26dollars.

$146.22 or 116.05 euros

Step-by-step explanation:

In Europe, you drive per day = 123 km

in one week = 123 × 7 = 861 km

Car's gas mileage = 31.0 miles per gallon

1 gallon = 3.8 liters

Car's gas mileage in liters = 31/ 3.8 = 8.16 miles per liter

total gas consumed in a week = 861 ÷ 8.16

                                                   = 105.5 liters

Cost of gas = 1.10 euros per liter

Total cost of gas used in a week = 105.5 × 1.10

                                                       = 116.05 euros

1 euro = 1.26 dollars

116.05 euros = 1.26 × 116.05

                    = $146.22

You would spend $146.22 or 116.05 euros on gas in one week.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
