Illusion [34]

Answer:

Sunil = 10 and Sushil= 40

Step-by-step explanation:

Present ages-

Sushil= 4x

Sunil= x

5 years ago-

Sushil = 4x - 5

Sunil = x - 5

4x - 5 = 7(x - 5) = 4x - 5 = 7x - 35

                        = -5 = 3x - 35

                        = 30 = 3x

                        = 10 = x

So substitute the xs for 10-

Present Sushil= 4 x 10 = 40

Find the percent of each type of sandwich sold.
elena55 [62]

Answer: 50% of the sandwiches were turkey, 30% were veggie and 20% were tuna.

Step-by-step explanation: The total number of sandwiches sold was 50 in all.

The sales according to type of sandwich were as follows;

25 Turkey

15 Veggie

10 Tuna

50 Total

Since there were 50 sandwiches sold and of these 25 were turkey sandwiches and another 15 were veggie sandwiches, then the remaining which is tuna sandwich is derived as 50 - [25 + 15] which equals 10.

To calculate the percentage per type of sandwich sold;

(a) Turkey is derived as

Percentage turkey = (25/50) x 100

Percentage turkey = 1/2 x 100

Percentage turkey = 50%

(b) Veggie is derived as

Percentage Veggie = (15/50) x 100

Percentage Veggie =  (3/10) x 100

Percentage Veggie = 30%

(c) Percentage tuna = (10/50) x 100

Percentage tuna = 1/5 x 100

Percentage tuna = 20%
