To answer the questions:
1. To find out how much each necklace costs, we can subtract the amount Brianna spent on bracelets ($23) from the total amount she spent ($65), since the rest of the money was spent on necklaces. Therefore, $65 - $23 = $42. Since she bought 3 necklaces, we can divide the total cost of necklaces ($42) by the number of necklaces (3) to find the cost of each necklace. $42 / 3 = $14. So, the answer is A. $14.
2. To determine how much Maria earned each time she babysat, we need to divide the total amount she earned ($216) by the number of times she babysat (5 + 3 = 8). Therefore, $216 / 8 = $27. So, the answer is C. $27.
3. To calculate the cost of 3 medium two-topping pizzas and 2 large one-topping pizzas, we need to add the costs of each pizza size and topping combination. Each medium two-topping pizza costs $13, so we multiply this by 3 to get the total cost of the medium pizzas: $13 x 3 = $39. Each large one-topping pizza costs $12, so we multiply this by 2 to get the total cost of the large pizzas: $12 x 2 = $24. Finally, we add the costs of the medium and large pizzas: $39 + $24 = $63. So, the answer is B. $63.
4. To determine how many more yards Tommy needs to run to score a point, we add the yards he has already run (18 + 29 = 47) and subtract this sum from the total yards required to score a point (60). Therefore, 60 - 47 = 13. So, the answer is A. 13 yards.
