Hey dude we’re both from Nepal so here’s the written worksheet hope it helps :)
Answer:
Step-by-step explanation:
Interest earned during the rest of 2 years and 6 months
40 + 40 + 40 = 120
he will be getting 1000 at the time of maturity ie after 2.5 years .
Total receipt = 1000 + 120 = 1120
investment made = 820
total receipt earned = 1120
profit made = 300
time = 2.5 years
profit = investment x rate of intt x time / 100
300 = 820 x r x 2.5 / 100 where r is rate of interest
r = 30000 / 820 x 2.5
= 14.63 % .
X + 3y = 7
x = -3y + 7
2x + 4y = 8
2(-3y + 7) + 4y = 8
-6y + 14 + 4y = 8
-2y = 8 - 14
-2y = - 6
y = -6/-2
y = 3
x + 3y = 7
x + 3(3) = 7
x + 9 = 7
x = 7 - 9
x = -2
solution is (-2,3)
Step-by-step explanation:
To find the answer we first multiply 129 by 0.7 since the price descresed 30 percent. each percent is equal to 0.01.
129 * 0.7 = 90.3
Then we multiply 90.3 by 1.0875 since that is the sales tax
90.3 * 1.0875 = 98.2
so the cost is 98.2
