Ryan has 30 stickers. Steven has thrice as many stickers as Ryan.   Terry has 20 more stickers than Steven. How many stickers do they have altogether?
Steven has 3 x 30 = <<3*30=90>>90 stickers.
And, Terry has 90 + 20 = <<90+20=110>>110 stickers.
Therefore, they have 30 +90 + 110 = <<30+90+110=230>>230 stickers altogether.
