A slice of carrot cake from The Cheesecake Factory contains 1,560 calories. This represents 75% of the average daily calorie requirement for many adults. Find the average daily calorie requirement for these adults.

Step 1 of 5

(1). Familiarize.

The energy in the slice of carrot cake is described in terms of the requirement of energy of an adult on a day.

So we let x calories = the requirement of energy of an adult on a day.

3/4 ( x ) calories

Then  is the energy in the slice of carrot cake.

The energy in the slice of carrot cake is 1560 calories.

2,080calories

Step-by-step explanation:

1569/75 = x/100 (cross multiplication)

(1560 * 100) / 75

= 2,080

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
