Answer:
25t + 100 = 550
Step-by-step explanation:
Notice that for every week, the balance increases by $25. That means t will be multiplied by 25 like this: 25t
There is already $100 on top of that, so add 100 to it like this: 25t + 100
Since Adam is saving for a $550 computer, this sum has to equal 550
25t + 100 = 550
If you want to find out how many weeks it will take to get that computer, subtract 100 from both sides
25t + 100 = 550
- 100 - 100
25t = 450
Divide both sides by 25
25t/25 = 450/25
t = 18
It will take Adam 18 weeks to save up and buy that computer.
Answer:
44378.496=44,379
Step-by-step explanation:
We can write the equation using a growth equation where:
- P is the starting value
- r is the percent or rate as a decimal
- t is years
We will substitute into the formula P=25,682, r=0.2 and t =3 for 3 years since 2018 is 3 years after 2015.

Answer:
She is left with $124 on her card.
Step-by-step explanation:
We begin with $200.
The purchases were $8, $63, $39.
She added $147 to her card.
She spent $113 on groceries.
Let's add the purchases first.
8+63+39=110.
$200-$110=$90.
Now we add $147 to the difference.
$147+$90=$237.
Finally, we subtract $113 from the sum.
$237-$113=$124.
