Answer:
The simpler way is:
SP = 0.85*RP
Step-by-step explanation:
Suppose that we have a given amount A. and now we take a given percentage, X%, off.
The new amount will be:
New amount = A - (X%/100%)*A = A*(1 - X%/100%)
This is the general formula.
In this case, we know that the store has advertised 15% off, then we have X% = 15%
Then if:
SP = sales price
RP = regular price
We will have the equation:
SP = RP - (15%/100%)*RP = RP - 0.15*RP
This is what Jill found, but if we use the general equation above, we will find that:
SP = RP*(1 - 15%/100%) = RP*(1 - 0.15) = RP*0.85
So we just need to multiply the regular price by 0.85 to get the sales price.
Answer:
Step-by-step explanation:
22. √125 is closer to √121 or 11
23. √23.5 is closer to √25 or 5
24. ∛59 is closer to ∛64 or 4 (cubed)
(4 cubed = 64, 3 cubed = 27)
25. ∛430 is closer to ∛512 or 8
(512 - 430 = 82
430- 343= 87)
26. y² = 55 is equal to y = √55, Closer to √49 or 7
27. d² = 95 is equal to d = √95, Closer to √100 or 10
28. p² = 6.8 is equal to p = √6.8, Closer to √9 or 3
29. ∛210 is closer to ∛216 or 6 (cubed)
30. ∛520 is closer to ∛512 or 8 (cubed)
