Laura has 1425 dollars in her bank account this amount reflects a 14% increase what was her original amo

$1425 multiplied by .14 (14% just move the decimal place over twice)

multiply these two numbers together and your result is $199.5 rounded up to $200.

Now you subtract $200 from 1425 and get $1225 which was the original amount

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
