Let’s solve each problem one by one.

Problem 1:
Michigan received
203.9 inches of snow in winter 1978–79.
In winter 1983–84, it received
13.3 inches less than that.
We need to find how much snow it received in 1983–84.
→ Subtract 13.3 from 203.9:
203.9
– 13.3
______
190.6
✔ So, Michigan received
190.6 inches in 1983–84.

Problem 2:
Eric bought:
- Fitness Tracker: $49.99
- Heart Rate Monitor: $36.95
Add them together:
49.99
+36.95
______
86.94
✔ Eric spent
$86.94 total.

Problem 3:
Monthly subscription: $17.00
For 12 months (1 year): 12 × 17 = ?
12 × 17 = 204 → So, yearly cost is
$204.00
He would spend
$178.00 by opting for subscription.
Wait — that doesn’t make sense. If monthly is $17, then 12 months = $204. But he says he’d spend $178 by subscribing? That’s *less* than $204.
So the question is: How much will he
save by opting for subscription?
→ Save = Regular cost – Subscription cost
= 204 – 178 =
$26.00
✔ He saves
$26.00 by choosing the yearly subscription.

Problem 4:
Sally used:
- 8.74 inches for husband’s bow
- 12.32 inches for daughter’s bow
Total ribbon used = 8.74 + 12.32

______
21.06
✔ Total ribbon used:
21.06 inches

Problem 5:
Heavy sedan fuel tank: 21.65 gallons
Compact car fuel tank: 16.7 gallons
Difference = 21.65 – 16.7
21.65
–16.70
______
4.95
✔ Difference:
4.95 gallons

Final Answer:
1) 190.6 inches
2) $86.94
3) $26.00 saved
4) 21.06 inches
