The exact number is 8,784 toffees but if you want me to estimate to the nearest tens then it would be 8,780
Answer:
I believe it is A
Step-by-step explanation:
first combine like terms so 2n + 7n which is 9n
so 9n + 7 = 13 + 3n + 8n
then combine on other side so 9n + 7 = 13 + 11n
then subtract 7 to 13 so 6
sp 9n + 6 = 11n
then subtract 9 to the other side so 2n
6 = 2n then divide all by 2
n= 3
45 because 30 divided by 2 is 15 the 15 times 3
