The owner of a clothing store buys t-shirts for c dollars each and sells them for p dollars each. last month she bought 600 t-shirts and sold 500 of them and made a profit of $2,800. this month she bought 400 t-shirts and sold them all and made a profit of $2,400. which system of equations can be used to determine the values of c and p?

600c - 500p = $2800

400c - 400p = $2400

Step-by-step explanation:

c = t-shirt costs

p = selling price

Profit = Cost - selling price

Last month = 600c - 500p = $2800

This month = 400c - 400p = $2400

500p - 600c = 2800

400p - 400c = 2400

Step-by-step explanation:

Given that the owner of a clothing store buys T-shirts for c dollars each and sells them for p dollars each

Then the profit or loss made on each T-shirts sold is p - c.

Last month she bought 600 T-shirts and sold 500 of them and made a profit of $2,800

This means that

500p - 600c = 2800

and

This month she bought 400 T-shirts and sold them all and made a profit of $2,400 then,

400p - 400c = 2400

Thus, the system of equations needed to determine the values of c and p would be

500p - 600c = 2800

400p - 400c = 2400

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

75

step-by-step explanation:

you do x-29=46 (the number of cantaloupes sold)

in order to find x, you have to find what minus 29 equals 46, meaning you'd have to add 29 to 46.

29+46=75

if you replace x with 75, the equation looks like:

75-29=46

x=75
