A restaurant customer left a $3.50 as a tip. The tax on the meal was 7% and the tip was 20% of the cost including tax. (Complete
Maru [420]

Answer: 17.50

Step-by-step explanation:

20% of x = 3.50

(20/100) x = 3.50  Divide top and bottom of the left number by 20

(20÷20) / (100÷20)  *  x = 3.50

(1/5) x = 3.50           Multiply both sides by 5  

x = 3.50 * 5

x = 17.50

The meal cost 17.50

When Javier and his father went to dinner, the bill was $34. If they tipped the waiter 20%, how much did they spend in total?
Kamila [148]

Answer:

Not sure if this is right, but I got $40.8.

Step-by-step explanation:

I first turned 20% into a decimal. (0.20).

Then I multiplied 0.20 and 34 which is 6.8.

I then added 34 since it’s the original cost to 6.8 since that’s the tip amount.

After that, you should get $40.8.
