Answer 3

"must spend at least 300"

so in other words, 300 or greater

how might we express this as an inequality?

Answer 4

So like this 300<10

Answer 5

we are using the variable d to represent the amount spent

d must be 300 or greater
since we include 300 we use ≥ rather than >

Answer 6

ok so \[300\ge10\]

Answer 7

we are using the variable d to represent the amount spent

Answer 8

"d must be 300 or greater" ---> d ≥ 300

Answer 9

Oh ok I understand now

Answer 10

in the second scenario the weight w must be 45 or less
see what you can get from tht

Answer 11

45\[45\le d\]

Answer 12

be careful about how you write it

the way you have it written, you are saying "d must be greater than or equal to 45"

Answer 13

ok

Answer 14

1. we are using the variable w, not d, as stated in the problem
2. w must be less than or equal to 45

write w first, then choose the appropriate inequality to represent "less than or equal to", then write 45

Answer 15

"write w first, then choose the appropriate inequality to represent "less than or equal to", then write 45"

1. we write "w"
2. "less than or equal to" is represented by ≤
3. write 45

putting these three steps together:

w ≤ 45
