OK. Great. Thanks for sharing. Do you have a question to ask ?
My hunch is that you want to know what the "number" is.
Here's how to set it up and solve it:
"a number" . . . . . . . . . . . . . . . Q
"The difference of
a number and 17" . . . . . . . . . . Q - 17
"eight times the difference" . . . 8 (Q - 17)
"is thirty" . . . . . . . . . . . . . . . . . . 8 (Q - 17) = 30
Eliminate parentheses on the left side:
8Q - 136 = 30
Add 136 to each side: 8Q = 166
Divide each side by 8 : Q = 20.75
The total price (c) would be the cost per pound ( $1.36 ) multiplied by the number of pounds bought (p)
C = 1.36p
Now replace p with the weight bought and calculate total cost:
c = 1.36(10)
c = $13.60
Answer:
1/5 = 0.2, 25% = 0.25, 4 out of 20 = 0.2
I think it’s 6.93 but idk man ♀️♀️♀️
