<u>Step 1:</u> Calculate the price of 11 oranges at $0.65 each.
11 × 0.65 = $7.15
<u>Step 2:</u> Consider the constraint: if Maribel only has a $10 bill, we have to deduct $7.15 from $10 to find our answer:
$10.00 - $7.15 = $2.85
<u>Step 3:</u> Write an equation based on our solution:
C = 10-0.65x ; Where:
* 10- indicates that we start with $10, and subtract from there. * C is the amount of change per purchase. * X is the number of oranges a customer buys.
Answers:
1. The customer receives $2.85 in change. 2. Given a case where a customer pays with one 10-dollar bill, their purchase amount can be calculated with C = 10-0.65x
They diagonal through the interior of the cube is the longest. The hypotenuse is the longest side of a right triangle. The diagonal of the cube is the hypotenuse of a right angle with legs that are diagonal of a face and an edge. The edges are the shortest. They are legs of a right triangle with the diagonal of a face as the hypotenuse.
