Susie wants to buy a snowboard that cause $530 she has already saved $98 for it she make 72 a week babysitting which and quality gives the maximum number of weeks W Susie needs to babysit and have enough money to purchase this snowboard.

 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.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
