I think the domain is -1 and the range is 2. You may want to double check though.
Add 3 to isolate y
3.8 + 3.8 = 1.9z - 3.8 + 3.8
7.6 = 1.9z
Divide by 1.9
4 = z
Ans: Sunny Market
Sunny Market as $3.20/5=$0.64 while and
Happy Mart $1.58/2=$0.79
Jacqueline is incorrect.
To find how much trash you can clean in 4 days if you already know how much trash you can clean in one day, multiply 1 2/3 (how much you can clean in one day) by 4.
Another way to write 1 and 2/3 miles is 5/3 (converting a mixed number to a single fraction). Then, 5/3 x 4 = 20/3. (To multiply fractions, just multiply across, leaving 5 x 4 in the numerator and 4 x 1 in the denominator.)
Jacqueline said you would be able to clean 19/3 miles but you can actually clean 20/3.
