Answer: 21/2 can not be simplified anymore!!
Step-by-step explanation:
So the formula for this is for every inch of width, you multiply by 2 to get the length.
Here, I made a table for it.
2×2=4
4×2=8
7×2=14
8×2=16 or 16÷2=8
X=amout the shirts cost
52=8+6.50+2x
add 8 and 6.5
52=14.5+2x
subtract 14.5 from 52
37.5=2x
divide 37.5 by 2
x=18.75
It cost $18.75 for each shirt.
Answer: Part a) 375 pounds, Part b) 8 words
Step-by-step explanation:
a)
<u />
Since n represents the number of words there are, we can plug in 20 for n into the equation to get:
C = 15*20 + 75 pounds
C = 300 + 75 pounds
C = 375 pounds
b)
Since C represents the cost of the advert, we can plug in 195 for C into the equation to get:
195 = 15n + 75
Subtract 75 from both sides:
120 = 15n
Divide both sides by 15:
n = 8 words
