To answer the question above, let x the number of hours for the two jobs to cost equal. Harry's charge can be expressed as 70x + 130 and that of Lou is 80x + 40. Equating both, 
  
                               70x + 130 = 80x + 40      ; x = 9

Thus, the job should take 9 hours for both charges to be equal.

Tony’s deposit earned $40.80 in simple over 3 years in an account with an interest rate of 1.7%. How much did Tony deposit?
Vsevolod [243]

Answer:

Tony's deposit was $800.

Step-by-step explanation:

we know that

The simple interest formula is equal to

I=P(rt)

where

I is the Final Interest Value

P is the Principal amount of money to be invested

r is the rate of interest  

t is Number of Time Periods

in this problem we have

t=3\ years\\ I=\$40.80\\r=1.7\%=1.7/100=0.017

substitute in the formula above

40.80=P(0.017*3)

P=40.80/(0.017*3)

P=\$800
