As you've got 15%, the best thing to do is to find 10%, then multiply it by 1.5. Once you've found the tip, you add this onto the cost of the meal.
Therefore, the total cost of $25 meal with a 15% tip is $28.75
Hope this helps :)
Answer:
Yes it can!!
Step-by-step explanation:
Obviously 3^2 is 9 because 3x3 lol
but since -3^2 is multiplying a negative times a negative, that makes a positive (9)
Answer:
I believe the answer is A. love your pfp btw
Step-by-step explanation:
12/400 is .03 or 3%
18. 5-2x = -4x+9
2x = 4
x = 2
perimeter = length of one side x 3
perimeter = [5-2(2)] x 3
= 3
19. 3(x-1) = 5x-6
3x-3 = 5x-6
-2x = -3
x = 1.5
perimeter = [3(1.5-1)] x 5
=7.5
20. 4/3x-⅓ = x+7
4x-1 = 3x+21 (multiply throughout by 3 to get rid of denominator on LHS)
x = 22
perimeter = (22+7) x 6
= 29 x 6
= 174
^ not sure about qn20 because i can’t tell if it’s x+7 or x divided by 7 it’s kinda blurry
246 x 18%=tip
Tip= 246 x .18
Tip=44.28
Tip+bill=total cost
44.28+246= 290.28
Or
246 x 1.18= 290.28
