Answer: 98 + 72w ≥ 530

Step-by-step explanation:

Hi, to answer this question we have to write an inequality with the information given:

She earns $78 per week (w) babysitting, and she already has $98 in savings.

Mathematically speaking:

78w + 98

Where w is the number of weeks.

Since the snowboard costs $530, the expression 78w + 98 must be greater or equal than 530.

98 + 72w ≥ 530

Solving:

72w ≥ 530 - 98

72w ≥ 432

w ≥ 432/72

w ≥ 6

She needs to babysit at least 6 weeks to buy the snowboard.
