Gracie went out to eat. She ordered chicken tenders for $11.50 and a soft drink for $1.25. She wants to leave a 20% tip. How much total money will Gracie spend on her meal plus tip?

Step-by-step explanation:

Given that Graice went out to eat and she ordered chicken tenders for $ 11.50 and a soft drink for $ 1.25 . She also wants to leave a tip of 20% of the total amount . So ,

=> Total amount that should be paid = Amount of chicken tenders + Amount of soft drink.

= $( 11.50 + 1.25 )

= $ 12.75

Now on this amount she wants to give a tip of 20 % . So the net amount wil be ,

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.
