This is on level 7th grade math that I am not understanding

The sale price would be $8.75

Step-by-step explanation:

To find that final price (which is the question that it is asking) would be to multiply 12.50 and .30 (or 30%) which would get you 3.75. Then you would subtract 12.50 by 3.75 which would get you $8.75. So $8.75 would be the final sale price.

This is the step by step with numbers.

12.50 × .30 = 3.75

12.50 - 3.75 = 8.75

Hope this helps!

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
