At the start of the week, Monique’s savings account had a balance of $326. She made a $45 withdrawal each day for seven days. During that week, she also made two deposits of $125 each. Which integer represents the balance in Monique’s account at the end of the week?

Solution:

Given that,

At the start of the week, Monique’s savings account had a balance of $326

She made a $45 withdrawal each day for seven days

Thus,

Remaining money = 326 - (45 x 7 )

Remaining money = 11

During that week, she also made two deposits of $125 each

Thus, balance in Monique’s account is:

Balance = 11 + 125 + 125 = 261

So, the integer represents the balance in Monique’s account at the end of the week is $ 261

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
