1. Lilly spends $5.84 per pound
Explanation:
The word "of" in math usually means to multiply. So you multiply 4/5 x 7.30, which gives us 5.84
2. Joe spends $2.60
Explanation:
Again, the word "of" in math usually means to multiply. So, you multiply 0.35 x 7.30, which equals 2.555. We then round 2.555 to 2.60, because you can't have $2.555.
3. The 3 spend $15.74
Explanation:
Now we know -
Joe spends $2.60
Lilly spends $5.84
John spends $7.30
To find the total amount spend, we add all 3 together. 5.84 + 7.30 + 2.60 = 15.74.
