Explanation:

Question 1

Step1: Add deposit to initial amount

$M = 8700 + 950$

Step2: Model variable deposit

$M = 8700 + D$

Step3: Write final model (no units)

$M = 8700 + D$

Question 2

Step1: Calculate total students in 3 years

$S = 31 \times 3$

Step2: Model students over Y years

$S = 31 \times Y$

Step3: Write final model (no units)

$S = 31 * Y$

Answer:

Question 1:
a) $8700 + 950$
b) $M = 8700 + D$
c) $M = 8700 + D$

Question 2:
a) $31 \times 3$
b) $S = 31 \times Y$
c) $S = 31 * Y$
