Math Club members are selling games and puzzles. They make a profit of $10 per game and $8 per puzzle. They would like to make a

AnnZ [28]

Answer:

a) $10x+8y \geq 200$

b) The members should sell at least 15 puzzles

Step-by-step explanation:

Let x represents selling games

and y represents puzzles

The statement given is: They make a profit of $10 per game and $8 per puzzle. They would like to make a profit of at least $200.

a) The inequality will be:

$10x+8y \geq 200$

at least 200 means the profit can be equal to 200 or greater than that.

b) If the members sell 8 games, how many puzzles would they have to sell?

Number of puzzles sold can be solved by solving the inequality $10x+8y \geq 200$

Put x =8 and find value of y

$10x+8y \geq 200\\10(8)+8y\geq 200\\80+8y\geq 200\\8y\geq 200-80\\8y\geq 120\\y\geq \frac{120}{8}\\y\geq 15$

So, the members should sell at least 15 puzzles to make the inequality true. because the profit should be at least $200.

The explicit formula for a sequence is

MAXImum [283]

Step-by-step explanation:

$\because \: a_n = - 1 + 3(n - 1) \\ \\ \therefore \: a_{55} = - 1 + 3(55 - 1) \\ \\ \therefore \: a_{55} = - 1 + 3 \times 54 \\ \\ \therefore \: a_{55} = - 1 + 162\\ \\ \huge \blue { \boxed{\therefore \: a_{55} = 161}}\\ \\$

Hence, the 55th term of the sequence is 161.

I need the answer for 6

Gnoma [55]

ME AGAIN!!! You should just let me do your homework from now on lol.

So, you have 4 red, 3 green and 1 yellow. Add all of those numbers together, you should get 8. How many green did you start with? You started with 3. So your answer is either 3:8, 3/8, or 3 to 8.

P.S: I can see the page fine. It isn't blurry. Hope that helped you!
