a takeaway sells 10 inch pizzas and 12 inch pizzas. what proportion sold were 10 inch pizzas in week 1. What proportion sold were 10 inch in week 2

In week 1, 69.15% of sales were 10-inch pizzas, and the remaining 30.85% were 12-inch pizzas; while in week 2, 71.09% of sales were 10-inch pizzas, and the remaining 28.91% were 12-inch pizzas.

Step-by-step explanation:

Given that a takeaway sells 10 inch pizzas and 12 inch pizzas, to determine what proportion sold were 10 inch pizzas in week 1 and what proportion sold were 10 inch in week 2, the following calculation must be performed:

Week 1 = 736 total sales

10-inch pizzas = 509

736 = 100

509 = X

509 x 100/736 = X

50,900 / 736 = X

69.15 = X

100 - 69.15 = 30.85

Thus, in week 1, 69.15% of sales were 10-inch pizzas, while the remaining 30.85% were 12-inch pizzas.

Week 2 = 1076 total sales

10-inch pizzas = 765

1076 = 100

765 = x

765 x 100/1076 = X

76500/1076 = X

71.09 = X

100 - 71.09 = 28.91

Thus, in week 2, 71.09% of sales were 10-inch pizzas, while the remaining 28.91% were 12-inch pizzas.
