There are 19 boxes of cherries. this is 5 less than twice the number of boxes of kiwis. how many boxes of kiwis are there?

All you have to do is 19+5 because it is 5 less. 19 is 5 less than the kiwis. so 19+5= 24.  

There is 24 boxes of kiwis

X is the number of boxes of kiwis
I think this is 5 less than twice the number of boxes of kiwis so 2x-5=19 solve for x
2x=19+5
2x=24
x=12
Explanation: if you double 12 boxes of kiwis is 24 and then subtract 5, you’ll get 19 is the number of boxes of cherries

$250 deductible means jane must pay the first $250 of her bill. so the insurance company paid = (80% of bill) - deductible = (0.8 x $2550) - $250 = $2040 - $250 = $1790 and jane's cost is = (bill) - (insurance payment) = $2550 - $1790 = $760
