Total titles(t)=450
1,075/450= 2.39~ 3 cans of paint
You can't have a can of half a paint, so it's 3 cans.
Answer: 30
Step-by-step explanation:
Answer:
Adult plate = 21 , child plate = 11
Step-by-step explanation:
number of adult plate = a , no of child plate = c
$487 = $19a + $8c (equation 1)
32 = a + c (equation 2)
Multiply equation 2 by 8 gets you:
256 = 8a + 8c (equation 3)
Solve equation 1 and equation 3 simultaneously:
487 = 19a + 8c (equation 1) minus
256 = 8a + 8c (equation 3) :
231 = 11a
a = 231/11
a= 21
Substitute a = 21 into equation 2 :
32 = 21 + c
c = 32 - 21
c = 11
So 21 adult plates and 11 child plates were sold.
Since we know that Zack must pay $11.00 per $100 monthly, we just need to divide the total amount of the loan, $1,087, by $100 to check how many times he must pay $11.00 each month:

Now we know that he must pay $11.00 10.87 times each month, so the last thing we are going to do to find his monthly payment is multiply both quantities:

We can conclude that Zack's monthly payment is $119.57
If we're just evaluating the function for the given values of x&y, the answer is 11.5
