Answer:
Walnuts = $1.75 per pound
Choc chips = $3.75 per pound
Step-by-step explanation:
In photo, is working out.
Solution:
Given: 35.052
The standard form is: 35.052
3 is in the tens place. 3 = 3 × 1
5 is in the tens place. 5 = 5 × 1
0 is in the tenths place. 0.0 = 0 × 1/10
5 is in the tenths place. 0.05 = 5 × 1/100
2 is in the tenths place. 0.002 = 2 × 1/1000
Since , the relation is linear .
Let equation is y = mx + c .
Putting , x = 0 and y = 32 .
32 = c .......( 1 )
Also , putting x = 100 and y = 212 .
We get :
212 = 100m + c .......( 2 )
Comparing equation 1 and 2 .
100m = 212 - 32
x = 1.8
Therefore , y = 1.8x + 32 .
Hence , this is the required solution .
45 minutes plus 45/2 minutes because of the fact that all the lawns are equal in size and he is mowing 1 1/2 full lawns with a full lawn taking 45 minutes
