Question

Alessandro currently has $2,400 in his savings account. He saves $250 per month. Bea currently has $1,750 in her account. She saves $350 per month. Write expressions to represent the amount in Alessandro and Bea’s bank accounts. Then solve how much more money than Alessandro will Bea have after 12 months?

Answer 1

Bea has $550 more money than Alessandro after 12 months.
Explanation:
So let start with writing the equation for Alessandro money. So we know that the current amount in his/her bank account has $2,400 and she saves $250 per month. So the equation that best fit these terms is:
y
=
250
x
+
2
,
400
Bea has $1,750 in his/her bank account and saves $350 per month. So the equation that best fit these terms is:
y
=
350
x
+
1
,
750
So for x for both of these equations is 12. So let plug the number in
Alessandro:
y
=
250
(
12
)
+
2
,
400

y
=
3000
+
2400

y
=
$
5400
after 12 months
Bea:
y
=
350
(
12
)
+
1750

y
=
4200
+
1750

y
=
$
5950
after 12 months
So subtracting $5950 and 5400 gives us a $550

hope this helps :p
