1.5= cost of one cupcake
each cupcake costs $1.50
Answer:
$35 x + $25 y ≥ $3200 x ≤ 120
Step-by-step explanation:
Because she needs to write before type the page, so that y≤x
∴ x≤120
$35 x + $25 y ≥ $3200 x ≤ 120
Answer:
the percent of rent is 25%
The key idea here is that
speed of plane in wind = (speed of plane in air) + (speed of wind)
Let
be the speed of the plane in still air, and
the wind speed. A tailwind blows in the same direction as the plane, so for the first leg of the trip, we have
![158\,\dfrac{\rm km}{\rm h}=s+w](https://tex.z-dn.net/?f=158%5C%2C%5Cdfrac%7B%5Crm%20km%7D%7B%5Crm%20h%7D%3Ds%2Bw)
For the return trip, the wind would blow in the opposite direction:
![112\,\dfrac{\rm km}{\rm h}=s-w](https://tex.z-dn.net/?f=112%5C%2C%5Cdfrac%7B%5Crm%20km%7D%7B%5Crm%20h%7D%3Ds-w)
Solve this system and you'll find
and

Answer:
total cost for Samantha to get her degree = $5,128.2
Step-by-step explanation:
Number of trimesters per year = 3
Number of years = 4
∴ Total number of trimesters throughout college = 3 × 4 = 12 trimesters
Tuition per trimester = $2.350
Total tuition (12 trimesters) = 2.350 × 12 = $28.2
cost of books per trimester = $425
cost of books throughout college (12 trimesters) = 425 × 12 = $5,100
total cost for Samantha to get her degree = total cost of tuition + total cost of books
total cost for Samantha to get her degree = 28.2 + 5,100
total cost for Samantha to get her degree = $5,128.2
