1. the real estate office sells 7 homes per month. complete the chart, then determine how many homes they sell in two years.

months: 2, 5, 8, 10

Explanation:

Step1: Calculate earnings for Ben

For each hour value, multiply by $8.50:

• $4 \times 8.50 = 34$
• $8 \times 8.50 = 68$
• $10 \times 8.50 = 85$
• $14 \times 8.50 = 119$

Step2: Calculate yards for receiver

For each second value, multiply by 9:

• $1 \times 9 = 9$
• $3 \times 9 = 27$
• $6 \times 9 = 54$
• $10 \times 9 = 90$

Step3: Calculate call costs for Mitch

For each minute value, multiply by $0.30:

• $5 \times 0.30 = 1.50$
• $12 \times 0.30 = 3.60$
• $24 \times 0.30 = 7.20$
• $30 \times 0.30 = 9.00$

Step4: Calculate homes sold & 2-year total

First, find homes per month value (7):

• $2 \times 7 = 14$
• $5 \times 7 = 35$
• $8 \times 7 = 56$
• $10 \times 7 = 70$

Then calculate 2 years (24 months): $24 \times 7 = 168$

Answer:

Problem 7 (Money Earned):

34, 68, 85, 119

Problem 8 (Yards):

9, 27, 54, 90

Problem 9 (Cost):

1.50, 3.60, 7.20, 9.00

Problem 10 (Homes Sold & 2-year total):

14, 35, 56, 70; 168 homes in two years
