C is the solution to the problem
Answer:
First deposit - Same amount
Second deposit - Sylvia
Third deposit - Sylvia
Step-by-step explanation:
Leroi put $200 in their account. They will add $40 every week.
Deposit 1: $240
Deposit 2: $280
Deposit 3: $320
Sylvia put $200 in their account. They will add 20% of the amount in the account each week.
Deposit 1: $240 (20% of $200 is $40)
Deposit 2: $288 (20% of $240 is $48)
Deposit 3: $345.60 (20% of $288 is $57.60)
So, Sylvia and Leroi have the same amount of money in their accounts after the first deposit. After the second and third deposit, Sylvia has more money.
$3.50×0.8=$2.80
$2.80×0.9=$2.52
The new price is $2.52

15x=7.5y
20x=10y
For problem3:
