Two problems here- 1) Find the total cost to the nearest cent, $100 dinner; 20% gratuity 2) Find the total cost to the nearest cent, 12300 car; 5% sales tax

Answers

In both of these problems you are asked to find a percentage of another number and then add it to that number... In math

"is" means =
"of" means ×

1) In the first problem 20% of 100 is, means
20% × 100 =
.20 × 100 = $20

now add it to the cost of the meal.

100 + 20 = $120 (final cost)

___________________

2) In the second problem 5% of 12300 is, means
5% × 12300 =
.05 × 12300 = $615

add this to the original price for the final cost...

12300 + 615 = $12,915

Kiyo bought a pizza for 12.75 and four medium drinks at Paulis pizza. Define a variable and write an expression to represent the total amount of money he spent. Then find the total cost if 1 drink is $3

Answers

a = cost of 1 drink $12.75 + 4a $12.75 + $12.00 = $24.75
let x represent cost of soda
y = 4x + 12.75
and if you put the three dollars into x
y = 12 + 12.75
so y = 24.75
