Samuel invests $2,600 into two savings accounts. One account earns 4% annual interest; the other earns 3.5% annual interest. At the end of 1 year, Samuel has earned $99.50 in interest. How much did he invest at each rate?

d is the answer

step-by-step explanation:

(sin 42)/31. = sinx)/37

sinx = 37 (sin42)/31

= 37× 0.66/31 = 0.787

x= 51.9

other angle opposite to y = 180-51.9-42

= 180- 93.9 =86.1

so

sin42)/31 = sin 86.1)/y

0.021 = 0.997 /y

y= 0.997/0.021 =47.47

1st part is 64,000,000

2nd part 500,000
