A one day trip to new york, mary spent $6.25 for breakfast and 8.95 for lunch. She can spend no more than an average of $8.50. H
zysi [14]

Mary spent $10.30 on dinner to stay in budget.

Step-by-step explanation:

Amount spent on breakfast = $6.25

Amount spent on lunch = $8.95

Amount spent on dinner = x

Average = $8.50

Average = \frac{Sum\ of\ values}{No.\ of\ values}

8.50 = \frac{6.25+8.95+x}{3}\\8.50=\frac{15.20+x}{3}

Multiplying both sides by 3

8.50*3=\frac{15.20+x}{3}*3\\25.50=15.20+x\\25.50-15.20=x\\x=10.30

Mary spent $10.30 on dinner to stay in budget.
