Question

Which situation can be modeled by the inequality 60−15x≥7?

Answer 1

Answer:

D

Step-by-step explanation:

To find a situation for 60−15x≥7, look for a story where 60 is a constant value that is decreasing by 15 for a number of times and where equal to or at least 7 is an option.

A. x would be weeks and it would decrease by 7x. This is not it.

B. 15 songs packages would have x be the number of packages not the price. This is not it.

C. This doesn't work either because if you want to owe them less than 7 it would have the sign < not >.

D. You have 60 to spend and you decrease it by $15 for each hat you buy till you save $7. This is it.

Answer 2

Answer:

Option D is correct.

Step-by-step explanation:

15 multiplied by x = 15x

15x Subtracted from 60= 60-15x

60-15x needs to be greater than or equal to 7

or we can say that 60-15x is at least 7

If we  look at the option D

let the  number of hats be x

cost of 1 hat =$15  

cost of 15 hats = 15x

total money = 60

so money left after buying x hats =60-15x

it should be at least 7

or we can write it as 60-15x >= 7
