Jason is saving up to buy a new iPhone that costs $1200. So far, he saved $350. He would like to buy the phone 5 weeks from now. What is the equation used to represent how much he must save every week to have enough money to purchase the iPhone?

• $1200+5x=350$

• $5x-350=1200$

• $350+5x=1200$

• $350-5x=1200$

Monica had $750 in a saving account at the beginning of the summer. She wants to have at least $225 in the account by the end of the summer. She withdraws (takes out) $35 each week for food, clothes, and movie tickets.

What inequality represents this statement?

• $750-35w\ge225$

• $750-35w\le225$

• $35w+750\ge225$

• $35w-750\le225$
