Answer: 216 cupcakes can be made
Step-by-step explanation:
<u>Given information</u>
36 pounds of dough in total
⅙ pound of dough per cupcake
<u>Set variables</u>
Let x be the number of cupcakes that could be made
<u>Set equations from given information</u>
Total = unit × number
36 = (1/6) × x
<u>Multiply 6 on both sides to isolate [x] variable</u>
36 × 6 = (1/6) × x × 6
216 = 1 × x

Hope this helps!! :)

The total cost of the item with sales tax will be $ 381.6.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
An item cost $360 before tax and the sale tax is 21.60.
Then the total cost of the item with sales tax will be
Total cost = 360 + 21.6
Total cost = $ 381.6
