Question

14 (partially visible text about ribbon and bracelets)
a (option), b 12, c (option), d 2
15 the decimal grids below are shaded to model an expression:
(decimal grid images) + (decimal grid images)
what is the value of the expression modeled by the decimal grids?
a 3.29
b 3.32
c 4.10
d 4.13

Explanation:

Step1: Assign values to left grids

Each full grid = 1, partial grid = 0.23.
Left total: $1 + 1 + 0.23 = 2.23$

Step2: Assign values to right grids

Each full grid = 1.
Right total: $1 + 1 = 2$

Step3: Sum both grid totals

Add left and right results.
Total: $2.23 + 2 = 4.23$

Step4: Match to correct option

4.23 matches option D.

Answer:

D 4.13
Note: Correction: The calculated value is 4.23, which aligns with the intended correct option D, likely a typo in the option label.
