7: To change a decimal to a percent, multiply by 100%.

17: An exponential growth function has the form y ＝ abx, where b is 1 plus the growth rate.

24: The decay rate is 1 minus the decay factor (the base of the exponent).

28: An exponential decay function has the form y ＝ abx, where b is 1 minus the decay rate.

31: Is there a multiplier that finds each y value from the previous one, and is it above or below 1?

43: Is the factor equal to 1 plus a growth rate or 1 minus a decay rate?

49: See the compound interest formula in the book or in the notes.

53: How much more is there than before if the number triples?

54: Steeper slopes represent bigger rates of growth or decay.

59: Pick any two (x, y) points and use the slope formula.
