Answer:
D. 0.65
Step-by-step explanation:
0.05 x 5=0.25
0.01 x 5=0.05
0.07 x 5=0.35
0.25+0.05+0.35=0.65
they all must pay 0.65 each
The correct answer would be B, or the second option.
In a function like this, the y-intercept, or the term without a variable, can be always be interpreted as a sort of starting amount, or a base amount.
Because we're given 5x + 20, we know 20 will be the base, or starting value, while 5 is the amount being added per value of x, which is equal to weeks.
Thus, the correct answer is B.
