                         Qty                  %                  = Qty (%)

Solution 1:          x                   .40                  .40(x)    

Solution 2:  <u>    96 - x  </u>         <u>   .25     </u>          <u>   .25(96 - x)   </u>

   Mixture:       96                  .37              .40x + .25(96 - x)

                                         96(.37)      =    .40x + .25(96 - x)

                                           35.52     =    .40x +   24 - .25x

                                           35.52     =    .15x +   24

                                            11.52     =    .15x

                                             76.8     =     x

Solution 2: 96 - x  = 96 - 76.8   = 19.2

Answer: 76.8 L of 40% solution, 19.2 L of 25% solution

An air conditioner is sold for $700 after a discount
Georgia [21]

100 - 12.5 = 87.5%

87.5% = $700

A country has 155 years of oil reserves at the current rate of consumption. Suppose that the demand for oil in the country is 2,
Alex17521 [72]

Answer:

  • a) 125,220,046 barrels
  • b) 71.25 years

Step-by-step explanation:

<u>Oil consumption:</u>

  • 2000000 barrels/year

<u>Rate of increase of consumption:</u>

  • 2% = 0.02 per year

<u>Total reserves </u>

  • 155*2000000 = 310000000 barrels

a) ....................................................................................

<u>Total oil consumption at the end of 42 years:</u>

  • 2,000,000
  • 2,000,000*1.02 =
  • 2.000,000*1.02^2
  • ...
  • 2,000,000*1.02^41

<u>Sum</u>:

  • 2000000*(1 + 1.02+ 1.02^2+ ...+ 1.02^41) =
  • 2000000*(1.02^41 - 1)/(1.02 - 1) = 125,220,046 barrels

b)  ....................................................................................

<u>Oil reserves will last:</u>

  • 2000000*(1.02^x - 1)/(1.02 - 1) = 310000000
  • (1.02^x - 1)/0.02 = 155
  • 1.02^x - 1 = 155*0.02
  • 1.02^x =1 +3.1
  • 1.02^x = 4.1
  • x log 1.02 = log 4.1
  • x = log 4.1 /log 1.02
  • x =  71.25 years
