Question

Wyatt was out at a restaurant for dinner when the bill came. He wanted to leave a tip of 19%. What number should he multiply the cost of the meal by to find the total plus tip in one step?

Answer 1

Wyatt should multiply with 1.19.

Explanation:

Forming the expression,

→ 1 + (19% of 1)

Now the required number is,

→ 1 + (19% of 1)

→ 1 + ((19/100) × 1)

→ 1 + (19/100)

→ 1 + 0.19 = 1.19

Hence, required number is 1.19.

Answer 2

• The cost of the meal should be multiplied by 1.19.

---------------------------------------

Let the cost of the meal be x.

Adding a tip of 19%:

• x + 19% =
• x + 0.19x =
• x (1 + 0.19) =
• 1.19x
