7. A toy store is selling a video game for a special price the week before Christmas. The store receives shipments Monday, Wednesday and Friday. The table below shows the number of video games shipped to the store and the number of video games sold during the week. Use this information to find the number of video games the store has left at the end of the week.

	Games Received	Games Sold
Monday	39	11
Tuesday		16
Wednesday	31	14
Thursday		11
Friday	41	11

The number of video games the store has left at the end of the week can be found by subtracting the total number of games sold from the total number of games received. The total number of games received is 39 + 31 + 41 = 111. The total number of games sold is 11 + 16 + 14 + 11 = 52. Therefore, the number of games left at the end of the week is 111 - 52 = 59.

Explanation

The number of video games the store has left at the end of the week can be found by subtracting the total number of games sold from the total number of games received. The total number of games received is 39 + 31 + 41 = 111. The total number of games sold is 11 + 16 + 14 + 11 = 52. Therefore, the number of games left at the end of the week is 111 - 52 = 59.

10. -112 is _____________ -115

Greater than

Less than

Equal to

-112 is greater than -115 because as we move towards the right on the number line, the value increases. Therefore, a negative number with a smaller absolute value is actually greater than a negative number with a larger absolute value. In this case, -112 has a smaller absolute value than -115, making it greater.
