Answer:
<h2>C. $1,689.00</h2>
Step-by-step explanation:
Let the amount spent by Tim be x and the amount spent by Nikko be y
If Tim spent $55 more than 2/3 of the amount that Nikko spent for his computer, then amount spent by Tim will be x = 55+2/3 y
Since the total amount that Tim and Nikko spent for their computers was $2,870 then;
x+y = $2,870
Substituting x = 55+2/3y into the equation above, we will have;
55+2y/3 + y = 2,870
(165 + 2y)/3 + y = 2,870
(165 + 2y+3y)/3 = 2,870
cross multiply
165 + 2y+3y = 3*2870
165+5y = 8610
5y = 8610-165
5y = 8445
y = 8445/5
y = 1689
<em>Hence Nikko spent a sum of $1,689.00 on his computer.</em>
Formula is I=PRT, where I is interest, P is original amount, R is rate, and T is time.
You’ve given me only R and P. At least three variables need to be defined in order to solve.

Answer:
x = 5 z = 94
Step-by-step explanation:
12x + 26 = 86
12x = 60
x = 5
360 - 172 = 188
z = 188 : 2 = 94
