leticia had $3.67. she earned $4.34. how much more does she need to buy a book that costs $10.00?

Explanation:

Step1: Calculate Calvin's total money

First, convert coins to dollars: 3 quarters = $0.25 \times 3 = 0.75$, 5 nickels = $0.05 \times 5 = 0.25$. Total money: $10 + 0.75 + 0.25 = 11.00$

Step2: Find tie cost

Subtract remaining money from total: $11.00 - 2.61 = 8.39$

Step3: Calculate Leticia's total money

Add her initial and earned money: $3.67 + 4.34 = 8.01$

Step4: Find needed money for book

Subtract her total from book cost: $10.00 - 8.01 = 1.99$

Step5: Calculate the multiplication

Multiply the two values: $1.18 \times 9 = 10.62$

Answer:

1. The tie costs $\$8.39$
2. $\$10.62$
3. Leticia needs $\$1.99$ more
