How much will 30 pencils cost if 10 pencils cost $0.59 and there is a $0.10 discount if your purchase 3 dozen?

we know 10 pencils cost 0.59, that means that 1 pencil alone costs 0.59 ÷ 10 = 0.059, close to 6 pennies really for each one.

well, the discount only occurs if we purchase 3 dozens, namely 36 pencils, however we're only buying 30, so no discount, all pencils are at regular price, namely 30 * 0.059 = 1.77.

step-by-step explanation:

yes

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
