Final answer:
To satisfy Mrs. Rodriguez's budget of $7.00 per trophy, she can choose option a) 7 trophies for $49.00 and option e) 5 trophies for $30.00.
Step-by-step explanation:
To determine which purchases will satisfy Mrs. Rodriguez's budget, we need to find the total cost of each option and compare it to $7.00 per trophy. Let's calculate:
- 7 trophies for $49.00: The cost per trophy is $49.00 / 7 trophies = $7.00. This option satisfies the budget.
- 12 trophies for $96.00: The cost per trophy is $96.00 / 12 trophies = $8.00. This option does not satisfy the budget.
- 9 trophies for $72.00: The cost per trophy is $72.00 / 9 trophies = $8.00. This option does not satisfy the budget.
- 3 trophies for $24.00: The cost per trophy is $24.00 / 3 trophies = $8.00. This option does not satisfy the budget.
- 5 trophies for $30.00: The cost per trophy is $30.00 / 5 trophies = $6.00. This option satisfies the budget.
Therefore, the purchases that will satisfy Mrs. Rodriguez's budget are options a) 7 trophies for $49.00 and e) 5 trophies for $30.00
