Parks department ordered a total of 100 bats and balls. The bats are $20 and balls are $4.50 each. The total invoice was $822.00 . How many of each item were ordered?

Number of bats ordered = 24

Number of balls ordered = 76

Step-by-step explanation:

Let,

x be the number of bats ordered

y be the number of balls ordered

According to given statement;

x+y = 100       Eqn 1

20x+4.50y = 822     Eqn 2

Multiplying Eqn 1 by 20

20(x+y=100)

20x+20y=2000     Eqn 3

Subtracting Eqn 2 from Eqn 3

(20x+20y)-(20x+4.50y)=2000-822

20x+20y-20x-4.50y=1178

15.50y = 1178

Dividing both sides by 15.50

Putting y=76 in Eqn 1

x+76 = 100

x= 100-76

x = 24

Hence,

Number of bats ordered = 24

Number of balls ordered = 76

stew reads at the fastest rate of 265 words per minute.

step-by-step explanation:

it's a given that felicia reads at 260 word per minute and on connie's graph we can see that she reads 200 words per minute. since stew's table tells us that he read 795 in 3 minutes, we can divide 795 by 3 to find out how many words he reads per minute.

795/3 = 265

stew reads 265 words per minute - he reads at the fastest rate since felecia reads at 260 words per minute and connie reads at 200 words per minute.

stew (265) > felecia (260) > connie (200)
