Sally wants to buy new fish for her fish tank. She buys goldfish and swordfish. Goldfish cost $.50 and swordfish cost $2.50. She buys 24 fish and spends a total of $40.00. How many of each type of fish does she buy? Create a system of equations to represent this problem. Then, solve the system using any method. (If anyone could also explain it that would be great :D)

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

48 / 6 = x

in this case, x will equal the amount of money in each card!

x therefore will be 8.

trent had $8 in each birthday card.

the answer is:

mean: 6

mad: 2.14
