Mr. Fishie bought a tank for $15 and 10 fish which cost $f each. If he gave the cashier two 20-dollar bills, what was his change

Gnesinka [82]

Answer:

$25 - $10f

Step-by-step explanation:

Fishie's name is fishy.

We know Mr. Fishie spent $15 on a tank. His 10 fish cost 10*$f. His total is:

Total =15 + 10*f

His change after 2 $20 would be:

$40 - ($15 - $10f), or

$25 - $10f

Answer this real-world question

Mrrafil [7]

Answer:

After 15 days they'll both have $10

Explanation:

100 (Xavier's total)- 6x (6 dollars every day) = 160 (Zach's total amount) -10x (10 dollars every day)

$100-6x=160-10x\\$

+10x on both sides

$100+4x=160$

-100 on both sides

$4x=60$

/4 on both sides

$x=15$
