Question

akira bought a new fitness tracker with her birthday money. each hour, she sets a target number of steps she wants to take. this hour, she has already taken 149 steps. akira still has 126 steps left before she reaches her target number. let t represent akira’s target number of steps. which equation models the problem?\\( t + 149 = 126 \\)\\( t - 149 = 126 \\)solve this equation to find akira’s target number of steps.\\( \square \\) steps\\( \text{submit} \\)\\( \text{work it out} \\)\\( \text{not feeling ready yet? these can help:} \\)

Explanation:

Step1: Select correct equation

The target steps $t$ minus steps taken equals steps left: $t - 149 = 126$

Step2: Solve for $t$

Add 149 to both sides: $t = 126 + 149$

Step3: Calculate final value

$t = 275$

Answer:

Correct equation: $t - 149 = 126$
Target steps: 275
