C. The cost of 5 notebooks is less than the cost of 3 + a $2 pen.

Process of elimination:
The greater or less than sign is open towards 3x + 2.

Get rid of the ones that say 5x is greater .

So A. And D. Are not an option

Now you have to put the pieces together.

Answer B. Sounds right until you get to the “$2-off coupon”

In the equation above it says 3x PLUS 2.
$2 off means subtraction. So we automatically know C is the only other answer.

Jerry scored 581 points by collecting 7 coins. In all, how many coins does Jerry have to collect to score a total of 996 points?
charle [14.2K]

Answer:

12 coins

Step-by-step explanation:

Points scored by collecting 7 coins = 581

Number of coins required to collect 996 points

Let Number of coins = c

7 coins = 581 points

c coins = 996 points

Cross multiply :

581 * c = 996 * 7

581c = 6972

Divide both sides by 581

581c / 581 = 6972 / 581

c = 12

Hence, number of coins required to collect 996 points is 12
