Answer 1

Using unit rates, we find that Tiana can bake 48 cookies with 6 scoops of flour, calculating first the unit rate of 8 cookies per scoop of flour, then multiplying by 6 scoops.

Step-by-step explanation:

The initial amount of cookies Tiana baked was 40 cookies with 5 scoops of flour. To determine how many cookies she can bake with 6 scoops of flour, we need to find the unit rate of cookies per scoop of flour.

First, we calculate the unit rate:

• 40 cookies ÷ 5 scoops of flour = 8 cookies per scoop of flour

Next, using the unit rate, we can find out how many cookies can be baked with 6 scoops of flour:

• 8 cookies/scoop × 6 scoops = 48 cookies

Therefore, with 6 scoops of flour, Tiana can bake 48 cookies.

Answer 2

6 scoops of flour, Tiana can bake 48 cookies.

To solve this problem using unit rates, we can find the rate of cookies per scoop of flour in the first scenario and then use that rate to calculate the number of cookies in the second scenario.

Find the unit rate of cookies per scoop of flour:

Unit rate= Number of cookies/ Number of scoops of flour

Unit rate= 40 cookies/ 5 scoops of flour

Unit rate=8 cookies/scoop of flour

Use the unit rate to calculate the number of cookies with 6 scoops of flour in the second scenario:

Number of cookies=Unit rate×Number of scoops of flour

Number of cookies=8 cookies/scoop of flour×6 scoops of flour

Number of cookies=48 cookies

Therefore, with 6 scoops of flour, Tiana can bake 48 cookies.
