I=prt
I=1640*0.06*6/12=49.2
A=1640+49.2=1,689.2
Use the substitution method
(9,90) y= 10x
90= 10(9)
90= 90
Answer is yes
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
