Answer:
1. D (5 fruit baskets)
2. C (4)
3. B (-10)
Step-by-step explanation:
1. Subtract 30 from 105 to get 75, as this is how much she paid for the annual membership fee. Then divide 75 by 15, this being the cost of the fruit baskets. Your answer would be 5, because 75/5=15.
2. Subtract 5 from 21. This would give you 16. Now you need to find out which number you would need to equal that 16. So 4x?=16. The answer would be 4.
3. Figure out what 5x? would need to be to get to -50. This would be -10, as -10x5=-50. Then just add in the 2, and since you're adding the positive 2 to a negative number, the negative number would be closer to 0, so -48.
