Heather loves roses.In her rose garden she has half as many pink roses as red,and four times as many red ones as white.There are 37 roses that are either yellow or white.Twenty are yellow.How many roses are in Heather's garden?
Help me out please anyone
think of it backwards...
37 may be white or yellow.. you know 20 are yellow, so 37-20 are white...
From there you multiply the white ones (37-20) times 4, and you get RED
From there you divide RED by 2, and you get PINK
Then you ADD yellow, white, red and pink..
140 roses. A LOT OF ROSES 😉
