This will make 7.5 x 1.009 higher than just 7.5 because 1.099 is higher than 1. And anything times 1 equals itself, so that means that if you times it by something higher than that, then the main number will go higher. If we do 0.951, then that won't work out because that will decrease the value of 7.5 since it is lower than 1. And if we do just 1, that will keep 7.5 to itself. So, the only option left is 1.099, and this option IS the right one.
