Answer 1

8 by 10 inches for the 1st problem

24/3 = 8

30/3 = 10

2nd problem:

Davis earned $5,138.50 for 4 weeks in February

add the two sales prices, multiply them by 0.015 to get $4,138.50. then add $1,000

(140,000+135,900)(0.015) + 4(250) = 5,138.50

3rd: Molly will have $515 at the end of a year. .03x500 = 15. add that to 500

4th: s=0.80p if it's 20% off, you pay 80% of the original price

center model is 9 inches. 10/500 = 1/50 = 9/450, ratios are the same

Monica would save $12.84 by waiting 25% off is $36 sales price. (1.07)(48-36) =12.84.

12 for Anna's hats. 3/8+3/8 = 6/8 = 3/4. 1-3/4 = 1/4. 1/4 of 48 =12 hats

-2x +5 is the simplification

15x = 35.55 - 15(1.75) divide by 15

x =2.37-1.75 = 62 cents for the same snack

4 weeks to get $16.60 at 4.15 per week. 16.6/4.15 = 4

for the last problem B is the answer. It's a line from 9 to the right of 9. It includes the point 9, so it's a darkened dot, not open
