2. Barak has 4 pet lizards. Each lizard eats 5 crickets a day. If a cricket costs 12 cents, which expression could be use to find the amount Barak will spend to feed his pet
lizards for one day?
CLE

The expression Barak could use to find the amount he will spend to feed his pet lizards for one day = Number of pets × number of crickets per pet × cost of each crickets

Step-by-step explanation:

Pet lizards = 4

Each lizard eats 5 crickets

4 pet lizards will eat = 4 × 5 crickets

= 20 crickets

A cricket = 12 cents

That is, $0.12

Cost of 20 crickets = 20 × $0.12

= $2

The expression Barak could use to find the amount he will spend to feed his pet lizards for one day

= Number of pets × number of crickets per pet × cost of each crickets

= (4) (5) (0.12)

= $2.4

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.

the answer would be c:   ax + b = ax + c
