Answer: If the price increases from $1,500 to $1,600 then the yield to maturity will decrease.
Step-by-step explanation:
If Yields in the market fell, Bonds would still be making the same coupon payments they always have been regardless of this fall. This will lead investors to buy more bonds which will have the effect of raising bond prices.
This therefore shows that Bond prices and Yields are inversely related. If one rises, the other falls. If the price of the security (bond) increases from $1,500 to $1,600 then it follows that the yield to maturity will decrease.
