Answer:
x = 12
y = 22
Total amount = $2596
Step-by-step explanation:
First let's find the value of each deposit until the 10th in relation to x and y:
1st: x
2nd: y
3rd: x + y
4th: x + 2y
5th: 2x + 3y
6th: 3x + 5y
7th: 5x + 8y
8th: 8x + 13y
9th: 13x + 21y
10th: 21x + 34y
Now, we can write a system with two equations and two variables:
2x + 3y = 90
21x + 34y = 1000
From the first equation: x = (90 - 3y)/2
Using this value of x in the second equation, we have:
21*(90 - 3y)/2 + 34y = 1000
945 - 31.5y + 34y = 1000
2.5y = 55
y = 22
Now we can find x:
x = (90 - 3*22)/2 = 12
Now, summing all the deposits, we have a total of 55x + 88y, which is equal to 55*12 + 88*22 = $2596
Step-by-step explanation:
If it cost $1200 to install 100 square feet of roofing, then it will cost $13200 to have 1100 square feet installed.
$1200/ 100 square feet multiply 11 on both sides
$13200/ 1100 square feet

61 because you always multiply first 60 x 0= 0 so now we have 60+1 which is 61
F = kry
f/kr = y
y = f/kr
Answer: y = f/kr
