Answer: Option D
D. 880 = 45d + 70; 18 days
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call d the number of days that Barry attends school
So the cost was:
Now we solve the equation for the variable d
The answer is the option D
To find x, we simply need to subtract the sum of the other two sides from 73.
35+11=46
73-46=27
So x = 27mm
1. substitute:
4+(7-5)
2. simplify:
4+2
3. evaluate:
6
the answer is 6.
Answer:
2 dollars
Step-by-step explanation:
5% interest is 1.05
1.05 times 40 equals 42
42-40 equal 2
So 2 dollars
You can write a subtraction problem as a division problem by subtracting one of the addends from the sum, then your other addend would be the answer.
Example :
5 + 6 = 11
11 - 5 = 6
