Question

ENTERTAINMENT For Exercises 19 and 20, use the following information.

Fairfield High spent d dollars for refreshments, decorations, and advertising for a dance. In
addition, they hired a band for $550.
19. Write an expression that represents the cost of the band as a
fraction of the total amount spent for the school dance.
20. If d is $1650, what percent of the budget did the band account for?

Answer 1

D + 550 = X

The band accounted for 25% of the budget.

Explanation:

Since Fairfield High spent D dollars for refreshments, decorations, and advertising for a dance, and in addition, they hired a band for $ 550, to write an expression that represents the cost of the band as a fraction of the total amount spent for the school dance and determine, if D is $ 1650, what percent of the budget did the band account for, the following calculations must be performed:

D + 550 = X

D = 1650

1650 + 550 = X

2200 = X

2200 = 100

550 = X

550 x 100/2200 = X

55,000 / 2,200 = X

25 = X

Therefore, the band accounted for 25% of the budget.
