A minor league baseball team plays 78 games in a season. If the team won 15 more than twice as many games as they lost, how many wins and losses did the team have?

Wins: 57 games

Losses: 21 games

Step-by-step explanation:

a + b = 78

a = 2b + 15

a = wins

b = losses

(2b+15) + b = 78

3b + 15 = 78

3b = 78 - 15

3b = 63

b = 63/3

b = 21

a = 2b + 15

a = 2*21 + 15

a = 42 + 15

a = 57

Check:

21 + 57 = 78

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

step-by-step explanation:

b and c are the correct answers.
