Let x represent the total cost, so i have this equation:
x=5c+12. Hope it help!
Given that this is based on simple interest, in the first case, investing at 4% for 3 years gives a total interest of 4%*3 = 12%. In the second case, investing at 6% for 4 years gives a total interest of 6%*4 years = 24%. (We can do this since the same principal is given to both.) This is exactly double that of the first case of 12%, so the second choice is the right answer.
Answer:
a) x = 7.5
b) x = 1
Step-by-step explanation:
a)
- (4x - 1)/2 = x + 7
- 4x - 1 = 2(x + 7)
- 4x - 1 = 2x + 14
- 2x = 15
- x = 15/2 or 7.5
b)
- 3x + 2 = (2x +13)/3
- 3(3x + 2) = 2x + 13
- 9x + 6 = 2x +13
- 7x = 7
- x = 1
