Hello,
I hope so far you and your family are staying safe and healthy!
We need to solve this step by step.
The college student has $700 in their account. But then she spends $165 on books from that money. So we need to Subtract that.
700 - 165 =535
However, later on, she deposits $190 to the same account. So we need to take the remain we had and add it to the new amount.
535 + 190 = 725
Thus,
There are $725 in the account.
I wish you all the best!

Answer:
$1.5 and $8.75
Step-by-step explanation:
Given data
let tables be x and chairs be y
The total cost to rent 3 chairs and 2 tables is $22
so
3x+2y=22----------1
The total cost to rent 5 chairs and 6 tables is $60
so
5x+6y=60---------2
the system of equation is
3x+2y=22----------1X 6
5x+6y=60---------2X 2
18x+12y= 132
- 10x+12y=120
8x+0y= 12
8x= 12
divide both sides by 8
x= 12/8
x=$1.5
put x= 1.5 in 2
5(1.5)+6y=60---------2
7.5+6y=60
6y=60-7.5
6y=52.5
divide both sides by 6
y= 52.5/6
y=$8.75
Counter example, Two Points, point A& B can be in the plane while point C is out side if the plane.
Step-by-step explanation:
A = P (1 + r/n) (nt)
A = the future value of the investment/loan, including interest
P = the principal investment amount (the initial deposit or loan amount)
r = the annual interest rate (decimal)
n = the number of times that interest is compounded per unit t
t = the time the money is invested or borrowed for
p = 3000
r = 5%/100 = .05 (has to be in decimal format)
n = 2
t = 1
A = 3000(1 + .05/2)⁽²ˣ¹⁾ note (make sure you use ^ (power of) for the 2x1)
use PEMDAS to work out problem

A = 3000(1 + .05/2)⁽²ˣ¹⁾
a = 3000(1 + .025)^²
a = 3000(1.025)^2
a = 3000 x 1.050625
a = 3151.875
she would have $3,151.88
