Jane's mother agreed to pay her $.50 for every flower bulb that Jane planted.  Jane planted 20 tulip bulbs and half that amount of iris bulbs.  She also planted 30 daffodil bulbs and three times that amount of crocus bulbs.  How much money did Jane earn?
20 tulip bulbs at $.50 each is 20*.50 $<<20*.50=10>>10.00
She planted half that amount of iris' so 20/2= <<20/2=10>>10 bulbs
10 iris bulbs at $.50 each is 10* .50 = $<<10*.50=5.00>>5.00
30 daffodil bulbs at $.50 each is 30*.50=$<<30*.50=15.00>>15.00
She planted three times that amount of crocus bulbs to 30*3 = <<30*3=90>>90 bulbs
90 crocus bulbs at $.50 = $<<90*.50=45.00>>45.00
All total, she earned 10+5+15+45 = $<<10+5+15+45=75.00>>75.00
