Answer:

Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.

Explanation:

Sandy gets $100 advance pay and $10 per hour for babysitting.

Let x denotes the number of hours then

10x + 100

Sandy wants to buy an Iphone for $450

10x + 100 = 450

Solving the above equation

10x = 450 - 100

10x = 350

x = 350/10

x = 35 hours

Therefore, Sandy needs to babysit for 35 hours to earn enough money to buy an Iphone.
