Answer 1

Answer: B and D

Explanation:

Each person has 5 weeks in which to save his or her money. The total amount of money that each member needs to save is $285

Member A works 8 hours per week at $6.15 per hour. Total number of hours in 5 weeks is 8 × 5 = 40 hours.

Total amount earned in 5 weeks would be

40 × 6.15 = $246

Member B works 10 hours per week at $5.85 per hour. Total number of hours in 5 weeks is 10 × 5 = 50 hours.

Total amount earned in 5 weeks would be

50 × 5.85 = $292.5

Member C: Works 7 hours per week at $7.25 per hour. Total number of hours in 5 weeks is 7 × 5 = 35 hours.

Total amount earned in 5 weeks would be

35 × 7.25 = $253.75

Member D works 9 hours per week at $6.35 per hour. Total number of hours in 5 weeks is 9 × 5 = 45 hours.

Total amount earned in 5 weeks would be

45 × 6.35 = $285.75

Member B and member D would reach their goals.
