Deon plans to watch 2 movies each month. Write an equation to represent the total number of movies n that he will watch in m months.
n = 2m
A pound of chocolate costs 7 dollars. Latoya buys p pounds. Write an equation to represent the total cost c that Latoya pays.
c = 7p
Dante took a taxi to the bus depot. He paid the driver the fee of $41 and gave her an additional 22% tip.
Let x be the amount Dante gave as a tip (in dollars). Using the values below, create a proportion that can be used to find x.
_______________________________________________________________
Use the proportion from part (a) to find the amount Dante gave as a tip. Do not round any computations.
_______________________________________________________________________
What was the total amount Dante gave the driver, including the tip? Do not round any computations.
Let's solve the proportion to find the amount Dante gave as a tip (x):
41 (fee) + x (tip) = 1.22 * 41 (total amount including tip)
41 + x = 50.02
x = 9.02
So, Dante gave the driver a tip of $9.02.
To find the total amount Dante gave the driver, including the tip:
Total amount = 41 (fee) + 9.02 (tip) = $50.02.
A doll is regularly priced at $18. For a sale, the price was reduced by 30%.
Let x be the reduction in price (in dollars). Using the values below, create a proportion that can be used to find x.
___________________________________________________________________________
Use the proportion from part (a) to find the reduction in price. Do not round any computations.

What was the price of the doll during the sale? Do not round any computations.
Let's solve the proportion to find the reduction in price (x):
$18 (original price) - x (reduction in price) = 0.7 * $18 (price during the sale)
18 - x = 0.7 * 18
18 - x = 12.6
x = 18 - 12.6
x = 5.4
So, the reduction in price of the doll during the sale was $5.4.
To find the price of the doll during the sale:
Price during the sale = $18 (original price) - $5.4 (reduction in price) = $12.6.
