sierra is going shopping to buy art supplies. she plans to buy 2 paint brushes at p dollars each , 6 bottles of paint at b dollars each , and 3 canvases at c dollars each . Write two different algebraic expressions to represent the total cost in dollars of these items sierra will buy .

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.

is only a line? i think so

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.

5+2x=a
