Answer:
A. -(3/10)x + 1 = 10
B. x = -30
Step-by-step explanation:
A. first, we know that we are multiplying a number (x) by -3/10 because that's the fraction of the number we are taking. Then, we add one to that number. After doing so, we are told that we get 10. Thus, -(3/10)x + 1 = 10
B. in solving this, first we subtract 1 from both sides, to get
-(3/10)x = 9
then, we divide both sides by -3/10 to get
x = -30
Answer:
The average price for all apples Mrs. Wise bought is $1.5 and this can be determined by using the unitary method.
Step-by-step explanation:
Given :
On Monday Mrs. Wise bought 3 lbs of apples at $4 per lb.
On Tuesday, apples were on sale for 20% off so she bought another 5 lbs.
If the price of 3 lbs apples is $4 then the price of 5 lbs apples is:
= $20/3
Now, determine the price of apples Mrs. Wise bought on Tuesday when apples are on 20% sale.
= $16/3
The average price is given by:
Average Price = $1.5
So, the average price for all apples Mrs. Wise bought is $1.5.
