9 = 1 + 8x - 8
9 = 8x - 7
9 + 7 = 8x
16 = 8x
16/8 = x
2 = x <==
Rowan raised 640 last year
this year he raised 15% more
percent means parts out of 100
15%=15/100=3/20
15% of 640
'of' can be translated as multiply
15%=3/20
3/20 times 640=1920/20=192/2=96
this is 15%
he raised 15% MORE SO
640+96=this year=736

Answer:
3438.
Step-by-step explanation:
6³ ÷ 4 + 2 × 9 (32 × 8 - 17 × 4)
= 6³ ÷ 4 + 2 × 9 (256 - 68)
= 6³ ÷ 4 + 2 × 9 × 188
= 216 ÷ 4 + 2 × 9 × 188
= 54 + 2 × 9 × 188
= 54 + 3384
= 3438
3438 is the answer.
