Answer:
9. 3.93miles
10. 7.42 cm
11. He doesn't have enough money to buy a hat.
12. $10.02
Step-by-step explanation:
9. ⇒
Yesterday walked=1.74 miles
Today walked=2.19 miles
Total walked both days=(1.74+2.19)=3.93miles
10.⇒
Total growth in a month was (12.72-5.3)=7.42 cm
11.⇒
After buying foods, Daniel has (20.39-8.76)=$11.63
The hat is $12
As, 11.63<12 (11.63 is less than 12)
So, he doesn't have enough money to buy a hat.
12.⇒
Penny has $35
Buying a hat and a scarf, Penny has spent (14.99+9.99)=$24.98
Now, Penny will have (35-24.98)=$10.02
Hope, this helps you.
Answer:
C
Step-by-step explanation:
(1) let there be x book and let the total cost be y dollars.
y=19.25x+40
y=16x+69.25
(2) 19.25x+40=16x+69.25
3.25x=29.25
x=9
9 silver book, 9 gold book.
(3) y=19.25x+40=19.25*9+40=213.25 dollars
both companies' total cost are 213.25 dollars.
