Answer:
<h2>22 hours and 10 hours </h2>
Step-by-step explanation:
let the jobs be x and y, so that
x+y=32--------1
9x+7y=248----2
x=32-y
substitute x=32-y for x in equation 2 we have
9(32-y)+7y=248
open bracket we have
288-9y+7y=248
-2y=248-288
-2y=-40
2y=40
divide both sides by 2 we have
y=40/2
y= 10 hours
subtitute y=10 for y in equation 1 to find x
x+10=32--------1
x=32-10
x=22
x=22 hours

Answer:
Rate = 0.45 or 45%.
Step-by-step explanation:
20184 = 9600(1 + r)^2
(1 + r)^2 = 20184/9600 = 2.1025
Taking square roots of both sides:
1 + r = 1.45
r = 1.45 - 1 = 0.45.
Answer:
If the quetion is how much money I earned on both days it would be 56.25
