Question

a bakery makes x donuts daily.each day 9x/10 of the donuts are sold and thr remaining are discarded.at these rates how many days will it take for the bakery to discard 360donuts in terms of x​

Answer 1

Answer:

I found the answer using both of the statements.

1) 10d + 5b = 12.90

2) d = b - 0.15

10(b-0.15)+6b=12.90

10b-1.5+6b=12.90

16b=14.4

b=0.9

[substitute for b in 2nd equation]

d=0.9-0.15=0.75

5(0.75)+3(0.9)=6.45, which is equal to 12.90(0.5)

Answer 2

Answer:

360 days

Step-by-step explanation:

x donuts are made.

9x/10 donuts are sold.

1x/10 are left and are discarded.

1x × 360 days= 360 days will take for the bakery to discard 360 donuts.
