#### Storyboard Text

• Really? Why?
• You﻿ know that bridge has a gap of 1.3cm right now?
• Wow, that's so cool﻿.
• And since it is 22 degrees celsius right now, the gap got bigger﻿.
• It was built to have room to expand when it get hot outside﻿.
• And yesterday it was 30 degrees and the gap was .9
• Hmm, that sounds like a challenge but I'll try.﻿
• ﻿You know, tomorrow the temperature is going to be 35 degrees celsius.
• Why don't you try and figure out how wide the gap is going to be tomorrow.﻿
• Ok, so she said that the temperature will be 35 degrees tomorrow..
• And today it was 22 degrees and yesterday was 30﻿
• ﻿So that means the gap changes, using an equation of y=-0.05x+-2.4
• ﻿So using that equation, the gap would be.. -2.35cm..!
