The least and greatest amounts that the two friends could spend on food are 100 and 140 respectively
Functions and values
Functions are expressions written in terms of letters known as variables. Given the equation that represents the food budget of two friends as shown;
1/2(x-120)=10
where x is the amount spent on food.
In order to determine the least and greatest amounts that the two friends could spend on food,
For the least amount
-(x-120) = 20
-x+120 = 20
x = 100
For the greatest amount
(x-120) = 20
x = 140
Hence the least and greatest amounts that the two friends could spend on food are 100 and 140 respectively

Answer:
230ml more punch can be added
Step-by-step explanation:
Given
- 135ml of orange juice is added
- 550ml of sparkling water is added
- 85ml of apple juice is added
- Volume of pitcher is 1000ml(=1 liter)
Therefore Volume added
= 135+550+85=770ml
As Volume added is less than volume of pitcher (770<1000)
More punch can be added to the pitcher
Volume of more punch that can be added= (1000-770)= 230ml

Answer: 3 / 20
Step-by-step explanation:
It is best to convert to decimals for such questions. It makes it faster.
Nick mowed 3/5 of the lawn yesterday. In decimals this is:
= 3/5
= 0.60
He then mowed another 1/4 this morning which is:
= 1/4
= 0.25
As these decimals must add up to one, subtract the above from 1 to find the proportion left:
= 1 - 0.6 - 0.25
= 0.15
Then convert back to fractions:
= 0.15 = 15/100
Lowest form would be gotten by dividing both the numerator and denominator by 5:
= 3 / 20
