Carolyn bought a dress that cost $45 and several pairs of pants, p, that were $9.99 each.  Michelle bought a jacket for $30 and pants that cost $11.50 each.  How many pairs of pants would the girls have to buy for Michelle’s total to exceed Carolyn’s total?

• 45 + 30 > 9.99p + 11.50p 

• 45p + 9.99 > 30p + 11.50

• 45 + 9.99p < 30 + 11.50p

• 45 + 9.99p > 30 + 11.50p

Belton is hosting a festival where vendors can pay to have a small booth or a large booth. The fee for a small booth is $85, and the fee for a large booth is $200. The city hopes to receive at least $3,700 in fees. Which inequality models this situation? Let x equal the number of small booths and y the number of large.

• 3700 - 200y = 85x

• 200y - 85x > 3700

• 85x + 200y ≥ 3700

• 85x + 200y ≤  3700
