The slope of the graph will correspond to the unit rate.
The unit rate is the amount it cost for one minute.
From the graph at x = 1, the rate is $4.75.
Answer:
The number is infinity
Step-by-step explanation:
Let the unknown number be x
if the number increased by three, then we have;
x + 3
Also quadrupling that number increased by five all divided by four is expressed as;
(4x+5)/4
Equating bith expressions and calculating x;
x+3 = (4x+5)/4
cross multiply;
4(x+3) = 4x + 5
4x+12 = 4x + 5
4x-4x = 5 - 12
0x = -7
x = -7/0
x = ∞
Hence the number is infinity
Scott spent $21 out of his $300
$21/$300 = 0.07
<u>Multiply the answer by 100</u> to get it as a <u>percentage</u>:
0.07*100 = 7
Therefore, Scott spent 7% of his paycheck on a gift
