Y + R + V = 42
but 4 YEARS AGO : (R-4) +(V-4) = Y
Replace Y in the 1st equation by: (R-4) +(V-4)
(R-4) +(V-4) + R + V = 42
2R - 2V - 8 = 42; 2R -2V = 50, or R+V=25
IF R+V =25 AND Y + R +V = 42, then Y + 25 = 42 and Y =17
Answer:
80%
Step-by-step explanation:
Answer:
i think it is 120
Step-by-step explanation:
4 multiplied by 30 is 120
1)
36/3 x 42/3 = 12yd x 14yd
12×14=168
you will need 168 square yards to recarpet the kindergarten.
2)
168×24.99=4198.32
it will cost $4198.32 to recarpet the kindergarten.
3)
3.5 is 35% of 10
4198.32÷3.5=1198.52
they will need to sell 1199 coupon books to completely pay for the the recarpeting.
.0091 rounded to the nearest hundredths is .01.
