Answer: In the hundreds place.
Step-by-step explanation:
1. You know that the first number has a 7 in its tenths place. This means that it is after the decimal point. You can write is as following:
x.7
Where x represents the other digits.
2. The second number has a 7 with a value that is 1,000 times greater than the value of the 7 in the first number, this means that you can know the place of the 7 in the second number if you multiply the first number by 1,000, or in other words, move the decimal point three places to the rigth. Therefore:
x.7*1000=7xx
3. As you can see, the 7 is in the hundred place in the second number.
Cost = .10 x ( n ) + 50
= .10(400) + 50
= 40 + 50
= 90
I hope this helps.
