Question

Shanelle already has $137 from babysitting. She needs at least $625 for a new tablet. Which inequality best represents this scenario?

t – 137 > 625
t + 137 ≥ 625
t + 137 < 625
t – 137 ≤ 625

Answer 1

t + 137 ≥ 625

Explanation:

Shanelle already have in her possession the sum of $137 from babysitting. She requires at least $625 for a new tablet. t is the remaining amount she needs to get the new tablet.

She already has $137 and to get the tablet she needs at least $625 . This means she needs nothing less than or equal to $625 to get the tablet. Recall t is the remaining amount needed to add to what she has to be able to reach the least amount required to purchase a tablet. Therefore , the sum of t and the amount of money already in her possession should be equal to or greater than $625.

To get the new tablet,

t + 137 ≥ 625
