Answer:
(a)The cost of ordering 3 Custom T-shirts is $39.
The cost of ordering 3 Fancy T-shirts is $75
(b)15 T-Shirts
Step-by-step explanation:
(a)Let n be the number of T-Shirts ordered
Custom T-shirts charges a one-time $15 set up fee and $8 per shirt ordered.
Cost, C=15+8n
Therefore, the cost of ordering 3 Custom T-shirts
= 15+8(3)
=15+24
=$39
Fancy T-shirts charges a one-time $60 set up fee and $5 per shirt ordered
Cost, C=60+5n
Therefore, the cost of ordering 3 Fancy T-shirts
= 60+5(3)
=60+15
=$75
(b)We are to determine the number, n at which the costs, C will be equal.
If C=60+5n and C=15+8n are equal, then:
60+5n=15+8n
8n-5n=60-15
3n=45
n=15
Therefore, the cost of both T-shirts will be equal when 15 T-shirts are ordered.
If she uses the blue book then she will need,
544/9 ≈ 61 pages
If she uses the red book the she will need,
544/7 ≈ 78 pages
So she will need 17 more pages if she uses the red book.
Hope this helps :)
Answer:
16
Step-by-step explanation:
Hey there i can help ya !
check the slope between the moving points
slope between (–6, –1) & (–3, 2) = 1 slope between (-3, 2) & (–1, 4) = 1 slope between (-1, 4) & (2, 7) = 1
the points are collinear and make an angle of 45 degrees with the x-axis
we can have an equation of a line passing through (-6,-1) and slope 1 as
(y + 1) = 1(x + 6) y = x + 5 is your linear model mostly
