Time used for the call to Zurich: ($5-$1.25)/$0.25=15 minutes
15minutes+3minutes=18minutes
Time used for the call to London: ($7.25-$1.25)/$0.25=24 minutes
24minutes+3minutes=27minutes
Difference between the two calls:27-18=9minutes
Answer:
the answer is 34
Step-by-step explanation:
first we put the equation together (4x^2+4x+1)by(2x^2+x-2)
so we multiply the formula together so we (4x^2+4x+1) (2x^2+-2) and that's how you get 34
This is dividing
So 1 mile has 1760 yards so in total
2 miles = 3520 yards and it takes 5 minutes to clean up 200 yards (We divide)
3520 ÷ 200 = 17.6 ( Now we multiply)
17.6 x 5 = 88 minutes or ( 1 hour and 22 minutes)
