You have space in your garden for 50 small flowering bulbs. Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $28.10 on bulbs. How many crocus bulbs
and how many daffodil bulbs can you buy?

you can buy 24 crocus bulbs and 26 daffodil bulbs.

Step-by-step explanation:

Let x represent the number of crocus bulbs that you can buy.

Let y represent the number of daffodil bulbs that you can buy.

You have space in your garden for 50 small flowering bulbs. It means that

x + y = 50

Crocus bulbs cost $0.25 each and daffodil bulbs cost $0.85 each. Your budget allows you to spend $28.10 on bulbs. It means that

0.25x + 0.85y = 28.1- - - - - - - - -1

Substituting x = 50 - y into equation 1, it becomes

0.25(50 - y) + 0.85y = 28.1

12.5 - 0.25y + 0.85y = 28.1

- 0.25y + 0.85y = 28.1 - 12.5

0.6y = 15.6

y = 15.6/0.6

y = 26

x = 50 - y = 50 - 26

x = 24

1) on the number line, -1.5 can be seen as going backwards 1.5.
there are -4 groups of -1.5
this means that you have to move in the opposite direction that you would normally move 1.5
4 groups of 1.5 is 6 (because you have to move in the positive direction)
6 is the answer

2) 975 feet below the surface
