Four chairs and two tables cost £218.
Six chairs and seven tables cost £587.
Find the total cost of buying twenty chairs and five tables.
Answers
Answer:
x = cost of a chair = £22
y = cost of a table = £65
£765
Step-by-step explanation:
Let
x = cost of a chair
y = cost of a table
4x + 2y = 218 (1)
6x + 7y = 587 (2)
Multiply (1) by 6 and (2) by 4
24x + 12y = 1,308 (3)
24x + 28y = 2,348 (4)
Subtract (3) from (4) to eliminate x
28y - 12y = 2,348 - 1,308
16y = 1,040
y = 1,040/16
y = 65
Substitute y = 65 into (1)
4x + 2y = 218 (1)
4x + 2(65) = 218
4x + 130 = 218
4x = 218 - 130
4x = 88
x = 88/4
x = 22
x = cost of a chair = £22
y = cost of a table = £65
Find the total cost of buying twenty chairs and five tables
20x + 5y
Substitute the values of x and y
20x + 5y
= 20(22) + 5(65)
= 440 + 325
= £765

Isaac invested $1,800 in an account paying an interest rate of 4.7% compounded continuously. Assuming no deposits or withdrawals are made, how much money, to the nearest hundred dollars, would be in the account after 15 years?
Answers
Answer:
First, convert R as a percent to r as a decimal
r = R/100
r = 4.7/100
r = 0.047 rate per year,
Then solve for A,
[tex]A = P\cdot e^{rt}\\\\A= 1800 \cdot (2.71828)^{(.047)(15)}, \ where \ e = 2.71828\\A = 3642.92[/tex]
The amount he receives after 15years $3,642.92
