Boxes of cereal normally cost £2.89 each, but a supermarket has a special offer: Boxes of Cereal
3 for the price of 2

Megan has £20 and she wants to get as many boxes of cereal as possible.

How many boxes can she buy?

10 boxes

Step-by-step explanation:

- 2.89*2= 5.78

20/5.78= 3.4...

which means you can spend 5.78 (the cost of two boxes) three times. now. if they're selling the boxes 3 for the price of two, you're actually getting 3*3.4 for your total amount you can purchase.  3*3.4= 10.2 obviously you can't get .2 boxes of cereal, so you round down to get 10 total boxes of cereal.

80 the answer is 80

step-by-step explanation:

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
