Answer: 15a^8
Step-by-step explanation: the exponent is 8
If you are rounding it to the nearest tenth then it would be 60% because the unit is above 5.
A) let h = number of half page ads and f = number of full page ads
40h + 75f = 800. Assuming budget is fully spent
h + f = 13
B) 75h + 75f = 975 (multiplying the second equation by 75)
35h = 175 (subtracting the first equation)
h = 5
Michael purchases 5 half page adverts
C) 5 + f = 13 (Substituting for h in second equation)
f = 8
Michael purchases 8 full page adverts
