Products: Each product can be mentally solved, we need to multiply each factor by the units digit and then add it to the product with the tenths, as follows

1. 8 \times 34  \implies (8\times 4)+ (8 \times 30)=32+240=272

2. 5 \times 47 = (5 \times 7)+ (5 \times 40)=35+200=235

3. 12 \times 43= (12 \times 3)+(12 \times 40)=36+480=516

4. 8 \times 33=(8 \times 3) + (8 \times 30)=24+240=264

5. 6 \times 4.4=60 \times 44=(60 \times 4)+(60 \times 40)=240+2400=2640 \implies 26.40

6. 7 \times 2.9= 70 \times 29=(70 \times +9)+(70 \times 20)=630+1400=2030 \implies 20.30

Distributive property: Remember, distributive property is about "distributing" the outside factor with each term in side the parenthesis, as follows

7. 6(n+4)=6\times n + 6\times 4=6n+24

8. 15(2+r)=15 \times 2 + 15 \times r=30+15r

9. 8(s+5)=8 \times s + 8 \times 5= 8s+40

10. 3(b+8)=3b+24

11. 5(6+b)=60+5b

12. 9(3+v)=27+9v

13. 7(r-7)=7r-49

14. 12(4-v)=48-12v

15. 11(3-s)=33-3s

The given table shows the prices. Ticket $8.50, Popcorn $5.25, Soda $4.00, Candy $3.75 and Nachos $6.

a. Each of four bought a tickets and a bag of popcorn, the money spent is

4(tickets)+4(popcorn)=4(8.50)+4(5.25)=34+21=\$55

They spend $55 in total.

b. 12 kids buy a box of candy and a soda.

12(candy)+12(soda)=12(3.75)+12(4)=45+48=\$93

They spent $93 in total.

c. The difference between three orders of nachos and three bags of popcorn.

3(nachos)-3(popcorn)=3(6)-3(5.25)=18-15.75=\$2.25

So, the difference between both orders is $2.25.

Answer: 440 grams for 1.54 is the better value
Explanation:
Take the price and divide by the number of grams
1.54 / 440 =0.0035 per gram
1.26 / 340 =0.003705882 per gram
0.0035 per gram < 0.003705882 per gram

Cost of 7 gallons=$24.50

Cost of 1 gallon=24.50/7=3.5

Cost of 15 gallons=15*3.5=52.5

Cost of 15 gallons will be $52.5
