Answer:
6.5 weeks.
55+50=105
35+60=95
It gets too wide when we double again.
55+ 100 =155
35+150=185
Therefore 55+70 =125
35+105= 125 Still too wide.
55+60=115
35+90= 125
The answer is between 6+ 7 weeks.
We then look at days.
Divide 55 weeks into 6.5 weeks less one day. Then apply 6.5
8.5 x 6.5 = 55 but when we plus 8.5+6.5=15
Divide 35 weeks into 6.5 weeks no remainder
5.5 x 6.5 = 35.75 =12
We see the ratio is 4:5
Banks round down and up for .5 answers.
Therefore both decimals round up so the answer is 6.5 weeks.
Step-by-step explanation:
Answer: it will take 4 months for the amount to be the same and the amount would be $95
Step-by-step explanation:
Let x represent the number if months it will take for the two accounts have the same amount of money.
Christiana opened her account with $55 and plans to deposit $10 every month. This means that the amount that in the account after x months would be
10x + 55
Marlena opened her account with $35 and plans to deposit $15 every month. This means that the amount that in the account after x months would be
15x + 35
For the amount in the accounts to be the same, the number of months would be
15x + 35 = 10x + 55
15x - 10x = 55 - 35
5x = 20
x = 20/5
x = 4
The amount would be
15 × 4 + 35
= 60 + 35
= $95
