Answer:
103
Step-by-step explanation:
To estimate a value you need to add 1 to the value each time a value after the value is above 5. For example the question above
102.831853072
Let's start from 2 the last number
Less than 5 so you won't be adding one to the number before it
It becomes 102.83185307
The next number is 7 it is greater than 5 so you add 1 to the number before it. Then it becomes
102.8318531. Continue like this till you get to 8 after the decimal point.
8 is above 5 so add to 102 making 103.
Answer:
Equation is S = 40w + 650
So S = 40(16) + 650
S = 640 + 650
S = $1,290
Step-by-step explanation:
this because each week (W) he adds $40 and the $650 is the initial amount in his savings account. So since 16 weeks went by, just multiply that by 40 and add 650 to that product.
