Question

Currently, the number of pizzas sold by a restaurant is 87. It is estimated that the number of pizzas sold will increase by 5% each hour. Find the total number of pizzas sold at the end of 7 hours.

Answer 1

Answer: 610.72 Pizzas

Explanation:

We need to find the value of 5% of 87, which after multiplication ( 5/100 x 87 ), we obtain as 4.35 .

Now, we’ll start adding this number to the present hour’s pizza count to obtain the next hour’s pizza count. Thus, the values will be-

87 pizzas (First Hour)

87 + 4.35 = 91.35 pizzas (Second Hour)

91.35 + 4.35 = 95.7 (Third Hour )

95.7 + 4.35 = 100.05 (Fourth Hour)

100.05 + 4.35 = 104.4 (Fifth Hour)

104.4 + 4.35 = 108.75 (Sixth Hour)

108.75 + 4.35 = 113.1 (Seventh Hour)

Now, just add em’ all up!

87 + 91.35 + 95.7 + 100.05 + 104.4 + 108.75 + 113.1 = 700.35

Therefore, 700.35 pizzas were sold at the end of 7 hours :)
