Last week, Danielle spent x dollars on lunch, three times as much on transportation as she did on lunch, and $4 less on books than she did on transportation. Write the expressions for the total amount Danielle spent last week on transportation and books.
If Danielle had $59 to spend last week, what is the greatest amount she could spend on lunch?

Danielle spent three times as much on transportation as she did on lunch, so we can call this 3x.

She spent $4 less than on books than she did on transportation -> 3x - 4

So, she spent x + 3x + 3x - 4 (simplified as 7x - 4).

Danielle had $59 to spend last week -> 7x - 4 = 59
Solve for x : (59+4)/7 = 9

So, she can spend at max $9 on lunch

Recheck : 9 + 27 + 27 - 4 = 63 - 4 = 59.

b) 1/3 * 1/5

step-by-step explanation:

each smallest part is 1/15 since the written one is 1/5 and it's divided by 3 equal parts. (1/5 )/3 = 1/15 = 1/3 * 1/5
