<h3>Answer:  7</h3>

=========================================================

Explanation:

The key states  7 \big| 4= 74

It means that a stem of 7 and leaf of 4 combine to the value 74

We're interested in scores greater than 90, so we'll be focusing on the stems of 9 and 10 only

  • Stem 9. Leaves 1,2,3,4,6,7.
  • Stem 10. Leaf 0

Stem9 has 6 leaves while stem10 has 1 leaf. That's 6+1 = 7 leaves total, which means we have 7 scores above 90. If there was a leaf of 0 for stem9, then we'd have to ignore it (since it forms the score 90). But we don't have to worry about that for this case.

Answer:

first blank: c(x) = 45x + 14

45x = 315

divide by 45 to leave x alone:

x = 7
