Question

With this given function D(h) = 8h + 25, how much dollars (D) did the student math after 45 hours? type in the correct answer *

Answer 1

$\\ \sf\longmapsto D(h)=8h+25$

$\\ \sf\longmapsto D(45)$

$\\ \sf\longmapsto 8(45)+25$

$\\ \sf\longmapsto 360+25$

$\\ \sf\longmapsto 385$

Answer 2

$\large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}$

Given function = D(h) = 8h + 25

__________________

Given that,

• D = dollars
• h = number of hours = 45.

__________________

Solving...

D(h) = 8h + 25

D(45) = 8(45) + 25

D(45) = 8 × 45 + 25

D(45) = 360 + 25

D(45) = 385 dollars

• The student should have got 385 dollars.
