Question

a algerbera 2 word problem to find out about stamos

Answer 1

Is that 40 of the 1 cent stamps and 3 times as many 25 cent stamps?

 

40 one cent stamps = 40($.01) = $.40

 

3 times as many 25 cent stamps = 3(40)($.25) = $30

 

Total spent = $30 + $.40 = $30.40

Answer 2

Remember that the money spent on each kind of stamp is:

     (price per stamp)*(number of stamps)

 

dollars = money on 40 cent stamp     +     money on 25 cent stamp

             $0.40s                       +               $0.25(3s)

 

dollars = $0.40s + $0.25(3s)

dollars = $0.40s + $0.75s

dollars = $1.15s
