The school has to computer labs. Each lab has 30 computers. A total of six computers in the school are not working. Which expression can you use to find the number working computers in the school

I'll do the first one for you. it isn't very hard at all.on number one, you have (50 × 3), which equals 150, and (3 × 3), which equals 9. after you establish that, you add 150 and 9 together. so, (150 + 9) equals 159.this means that 53 × 3 = 159.
