Question

charlie saves 70% of his earnings from his part-time job. he saves $56 each week. use a 10-squares model to determine how much charlie earns each week.
first, shade the 10-squares model to show 70% of the entire model.
select the cells to shade 70%.

Explanation:

Step1: Define 1 square's value

Since 7 shaded squares (70% of 10) = $56, 1 square = $\frac{56}{7} = 8$

Step2: Calculate total earnings

Total squares = 10, so total earnings = $10 \times 8 = 80$

Step3: Shade 70% of the model

7 out of the 10 squares are shaded to represent 70%.

Answer:

Shade 7 of the 10 squares.
Charlie earns $80 each week.
