Explanation:

Question 1

Step1: Calculate revenue from umbrellas

Revenue = Price × Quantity, so for umbrellas: \( 17 \times 25 = 425 \)

Step2: Calculate revenue from hoodies

For hoodies: \( 50 \times 58 = 2900 \)

Step3: Sum the two revenues

Total = \( 425 + 2900 = 3325 \)

Number model with unknown: Let \( x \) be total money spent on umbrellas and hoodies. \( x = (17 \times 25) + (50 \times 58) \)

Step1: Calculate revenue from key chains

\( 5 \times 6490 = 32450 \)

Step2: Calculate revenue from knit hats

\( 13 \times 99 = 1287 \)

Step3: Sum the two revenues

Total = \( 32450 + 1287 = 33737 \)

Number model with unknown: Let \( x \) be total money spent on key chains and knit hats. \( x = (5 \times 6490) + (13 \times 99) \)

Step1: Calculate revenue from key chains

\( 5 \times 6490 = 32450 \)

Step2: Calculate revenue from caps

\( 9 \times 3512 = 31608 \)

Step3: Find the difference

Difference = \( 32450 - 31608 = 842 \)

Number model with unknown: Let \( x \) be the difference. \( x = (5 \times 6490) - (9 \times 3512) \)

Answer:

(with unit): \$3325
