If she will buy 35 T-shirts, 45 pairs of shorts, and 25 windbreakers, what will be her total cost?

svetoff [14.1K]

Answer:

$Total\ Cost = \$973.75$

Step-by-step explanation:

Given (Missing part of question)

T-shirts = $7.50

Shorts = $9.00

Windbreakers = $12.25

Required

Determine the total cost

Total Cost is calculated as follows;

$Total\ Cost = Costs\ of\ T-Shirts + Costs\ of\ Shorts + Costs\ of\ Windbreakers$

$Total\ Cost = 35 * \$7.5 + 45 * \$9.00 + 25 * \$12.25$

$Total\ Cost = \$262.5 + \$405.00 + \$306.25$

$Total\ Cost = \$973.75$

How to find the other endpoint of a line when only given the first endpoint and the midpoint?

Schach [20]

If we have a line, and the endpoints are(x₁,y₁) and (x₂,y₂), the midpoint will be:( (x₁+x₂)/2 , (y₁+y₂)/2 );

Data:
Endpoint₁: (2,-3)
Midpoint: (6,6)

Therefore:

(2+x₂)/2=6
2+x₂=12
x₂=12-2
x₂=10

(-3+y₂)/2=6
-3+y₂=12
y₂=12+3
y₂=15

Answer; the other endpoint of a line will be (10,15)
