Company A charges $32 per person to host a banquet. Company B charges an initial fee of $30 and charges $30 per person. At what number of people will Company B be the cheaper option?

At 16 people company B will be the cheaper option

Step-by-step explanation:

Assume that the number of people is x

∵ Company A charges $32 per person to host a banquet

∵ The number of people is x

∴ The cost of company A = 32x

∵ Company B charges an initial fee of $30 and charges $30 per person

∵ The number of people is x

∴ The cost of company B = 30x + 30

∵ Company B be is the cheaper option

→ That means the cost of company B < The cost of company A

∴ 30x + 30 < 32x

→ Subtract 30x from both sides

∵ 30x - 30x + 30 < 32x - 30x

∴ 30 < 2x

→ Divide both sides by 2

∴ 15 < x

→ 15 smaller than x means x is greater than 15

∴ x > 15

→ To make company B cheaper, the number of people should be > 15

∵ The first integer greater than 15 is 16

∴ At 16 people company B will be the cheaper option

we need the options

step-by-step explanation:

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
