Company A charges \$55 per day plus \$0.35 per mile to rent a car. Company B charges \$50 per day plus \$0.40 per mile. Jack wants to rent a car for three days. How many miles should Jack be traveling so that Company A is less expensive than Company B?

• ALGEBRA -

The volume of a rectangular slab of concrete needs to exceed 72 cu. ft. If the length is 12 feet and the width is 8 feet, how thick does the concrete slab need to be?

• ALGEBRA -

“Collin left the party one half hour before Gabriel. Terrence left an hour and a half later than Gabriel. Together the three of them stayed more than four hours. How long did they each stay at the party?”

• ALGEBRA -

Laura found \$2.15 in quarters and nickels in the bottom of her purse. There were seven fewer quarters than nickels. How many nickels and quarters did she find?

• ALGEBRA -

company A:
cost = .35m + 55

company B:
cost = .4m + 50

solve
.4m+50 = .35m+55
.05m = 5
m = 5/.05 = .....

Please do not post a new problem as an appendix to a previous post.
Tutors will think it has been answered and might ignore the entire post

second Problem:

let the thickness be x ft

so 12(8)x ≥ 72
x ≥ 72/96
x ≥ 3/4 ft

• ALGEBRA - don't post sequences of questions -

You are more likely to get each answered if you post each question as an individual posting
