Answer:
Number of cheaper dresses sold is 35
Number of expensive dresses sold is 15
Step-by-step explanation:
Given:
Cost of cheaper dresses = $90
Cost of expensive dresses = $140
Total cost of the dresses = $5250
To Find:
Number of cheaper dress = ?
Number of expensive dress = ?
Solution:
Let
The number of cheaper dresses be x
The number of expensive dresses be y
(Number of cheaper dresses X cost of cheap dress) + (Number of Expensive dresses X cost of expensive dress) = $5250
= $5250
It is given that the 20 more of the cheaper dresses than the expensive dresses is sold
So,
number of cheaper dress = 20 + number of expensive dress
x = 20 + y---------------------------------------(1)
y = 15
Substituting y in (1)
x = 20 +15
x= 35
Answer:
I think it's 4
Step-by-step explanation:
y=mx+b is the formula
m=slope
b=y intercept
the slope is 2
and the y intercept is -3
so the answer is 4, y=2x-3
The complete question in the attached figure
we know that
the ratio is 1:3
that means
(1+3)=4 liters
To prepare 4 liters of fruit punch use 1 liter of orange juice and 3 liters of <span>pineapple
so
</span><span>to Make 3 Liters of fruit punch
</span><span>the proportion to find the pineapple liters will be
3/4=x/3------> x=9/4-----> 2.25 liters of </span><span>pineapple
</span>
the answer is2.25 lt pineapple
