The Martinez family ate at a restaurant.

The cost of the meal was $34.50.
The sales tax was 6% of the cost of the meal.
They left a tip of 15% of the cost of the meal plus tax.
What was the total cost of the meal, tax, and tip?

Answers

Answer:

$42.06

Step-by-step explanation:

step 1: find the 6% of 34.50; by multiplying 34.50 x 0.06 ( 0.06 = 6/100 or 6%).

34.50 x 0.06 = 2.07

Step 2: 2.07 + 34.50 = 36.57 -----Total cost of meal + 6% tax.

Step 3: find 15% of 36.57

36.57 x 0.15 = 5.4855

Step 4: 36.57 + 5.49 (rounded because money only has two decimal places)

Answer:

$42.06

Richard gets a bonus of 30% of £130 Connor gets a bonus of £40 work out the difference between the bonus Richard gets and the bonus Connor gets

Answers

Answer:

Please check the explanation.

Step-by-step explanation:

Given that Richard gets a bonus of 30% of £130.

Thus,

Richard's bonus = 30% of 130

                           = 30/100 × 130

                           = 39

Thus, Richard gets £39.

Given that Connor gets a bonus of £40.

The difference between the bonus Richard gets and the bonus Connor gets.

Difference = Connor Bonus - Richard Bonus

                 = £40 - £39

                 = £1

It means Connor gets  £1 more than what Richard gets.

Therefore, the difference is: £1

Answer: n=7+1/2

Step-by-step explanation:

We move all terms to the left:

We move all terms containing n to the left, all other terms to the right

2n=15

n=15/2

Answer:

They are not congruent because they are not facing the same way.

Step-by-step explanation:

SAS stands for "side, angle, side" and means that we have two triangles where we know two sides and the included angle are equal. If two sides and the included angle of one triangle are equal to the corresponding sides and angle of another triangle, the triangles are congruent.

That is which postulate proves congruency.

Please make this Brainliest.

Answer:

They are not congruent would be my guess cause the sides are not the same my bad if it is wrong lil br uh

Step-by-step explanation:

In geometry, two figures or objects are congruent if they have the same shape and size, or if one has the same shape and size as the mirror image of the other. This means that either object can be repositioned and reflected (but not resized) so as to coincide precisely with the other object.
