Answer:

your question doesn't make sense if an electrician came to your house it would cost $40 then $55 dollars per hour but there is no way that you can solve that (40+(55•2)=150+55=205 which is already over $190 dollars

You saved $1,240 and your sister agrees to put it in a savings account at her credit union so you can earn interest. You earned
leva [86]

The amount after 2 years is $2,295.

Given that,

  • The invested amount is $1,240.
  • The rate of interest is 8%.
  • The number of years is 2 × 4 = 8

Based on the above information, the amount after 2 years is

Future value = Present value ×(1 + rate of interest)^number of years

= $1,240 × (1 + 0.08)^8

= $1,240 × 1.08^8

= $2,295

Therefore we can conclude that the amount after 2 years is $2,295.
