To convert from Celsius to Fahrenheit, we can use the formula:
°F = (°C × 9/5) + 32
Considering the given temperature range of -3°C or warmer, we can calculate the equivalent Fahrenheit temperatures.
For -3°C:
°F = (-3 × 9/5) + 32 ≈ 26.6°F
Therefore, Andrea's sleeping bag is designed for temperatures of 26.6°F or warmer.
The correct answer is C) 26.6°F or warmer.

To find the area of the trapezoid, we can use the formula:
Area = (base1 + base2) * height / 2
For the given trapezoid with a height of 11 cm and bases of 19 cm and 13 cm, the area can be calculated as:
Area = (19 + 13) * 11 / 2 = 32 * 11 / 2 = 176 / 2 = 88 cm^2
Since sequins cost $0.70 per cm^2 of coverage, the cost of all the sequins can be found by multiplying the area by the cost per cm^2:
Cost = 88 cm^2 * $0.70/cm^2 = $61.60
Therefore, the cost of all the sequins is $61.60.
