well 6 out of 42 is 1/7
double 42 and get 84.
Now to keep it even, you have to multiply 6x2
Jessica is purchasing a new car whose MSRP is $19,750. She is trading in her old car for $8100.
Without the upgrade package and delivery charge , the cost of her car is
19,750 - 8100 = $11650
upgraded cost = $6000 and Vehicle delivery = $600. we add the upgraded cost and delivery cost.
Total cost of car = 11650 + 6000 + 600 = $18,250
-80x is the the problem
In this case, x=7
-80 times 7= -560
So -560 would be the integer that represents the depth of the submarine after 7 minutes.
