Seven years ago, kodi found a box of old baseball cards in the garage. since then, he has added a consistent number of cards to
Katena32 [7]
(3,52)(7,108)
slope = (108 - 52) / (7 - 3) = 56/4 = 14

y = mx + b
slope(m) = 14
(3,52)...x = 3 and y = 52
sub and find b, the y int (the original amount of cards)
52 = 3(14) + b
52 = 42 + b
52 - 42 = b
10 = b

so ur equation is y = 14x + 10....with x being the number of years and y being the total cards. <== ur equation is y = 14x + 10

He started with 10 cards....and has been adding 14 cards every year.

so after 10 years...
y = 14(10) + 10
y = 140 + 10
y = 150 <== after 10 years, he will have 150 cards

Susan decided to start a bracelet business. She spent $17.75 on supplies for her
Snezhnost [94]

Answer:

Given that:

Susan spent on supplies = $17.75

Earning of june = 24 * $3.25

Earning of June = $78

1/4 of earning = 1/4 * 78

1/4 of earning = $19.5

So Susan will set $19.5 aside for supplies of next month and remaining amount she will have is : 78 - 19.5 = $58.5

i hope it will help you!
