Alessandro currently has 2,400 in his savings. he saves $250 a month. bea has $1,750 in her account. she saves $350 a month. how much more money will bea have in her account than alessandro after 12 months

$550

Step-by-step explanation:

Alessandro has 2,400 presently

since he saves $250 a month , after 12 months , he would have saved

12 x $250 = $,3000 ,with his present savings , he will be having  

$2400 +$3000 = $5400

Also , Bea has $1,750 presently, since she saves $350 a month, after 12 months she would have saved

12 x 3550 = $4200

In total , she will be having

$4200 + $1 ,750 = $5950

Bea will have $5950 - $5400 in her account than Alessandro

= $550

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents
