Question

Sienna has $8 and is saving $3 per week. Jacob has $6 and is saving $4 per week. Which model represents the equation that can determine when Sienna will have the same amount of money as Jacob?
8 Negative x tiles and 3 positive 1 tiles = 6 positive x tiles and 4 positive 1 tiles

8 x tiles and 3 positive 1 tiles = 6 x tiles and 4 positive 1 tiles

3 x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles

3 negative x tiles and 8 positive 1 tiles = 4 x tiles and 6 positive 1 tiles

Answer 2

Answer:

B

Step-by-step explanation:

From the given information:

Sienna has $8 denotes the unit blocks of x tiles. So, she saved $3 per week.

This implies that:

8x + 3(1) = 8x + 3

Also,

If Jacob as well had $6 which implies 6x unit block of tiles while he saved $4;

i.e.

6(x) + 4(1) = 6x + 4

So;

the model that can determine when Sienna will have the same amount as Jacob is:

8x + 3 = 6x + 4
