Let the number of orders that were delivered on time be \(a\).
\(3.5a - 4.3(210-a) = 532.2\)
Now we should check our answers:
If \(184\) orders were delivered on time, Peter would have
If there were \(184\) orders that were on time, there were
\(210-184=26\) late orders.
We should now subtract
from Peter's \($644\).
\(184 \) orders were delivered on time.
Let the cost of a candy bar be x and the cost of a piece of bubble gum be y.
The total cost:
The candy bar costs a dollar more than the bubble gum.
In other words,
Now, we can replace the value of x with the above equation so that the first equation contains only one variable:
Simplify and solve:
The piece of bubble gum costs 25 cents.
Hope this helped!
Let x be the largest integer.
First find the sum of the integers:
Now, since the sum or 7x - 21 is 21 times the largest of the integers or x, we can solve for x:
Now we know the largest of the integers is -1.5.
To find the smallest integer, all we need to do is subtract 6 from -1.5:
The smallest integer Pearl wrote down was -7.5.
