You have space in your garden for 60 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $39.00 on bulbs. How many crocus bulbs and how many daffodil

The question is incomplete:

You have space in your garden for 60 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $39.00 on bulbs. How many crocus bulbs and how many daffodil bulbs can you buy?

You can buy 20 crocus bulbs and 40 daffodil bulbs.

Step-by-step explanation:

From the information provided you can write the following equations:

x+y=60 (1)

0.25x+0.85y=39 (2), where:

x is the number of crocus bulbs and y is the number of daffodil bulbs.

First, you can solve for x in (1):

x=60-y (3)

Then, you can replace (3) in (2):

0.25(60-y)+0.85y=39

15-0.25y+0.85y=39

0.60y=39-15

y=24/0.60

y=40

Finally, you can replace the value of y in (3) to find the value of x:

x=60-40

x=20

According to this, the answer is that you can buy 20 crocus bulbs and 40 daffodil bulbs.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
