On Monday at work, David produces $w$ widgets per hour, and works for $t$ hours. Exhausted by this work, on Tuesday, he decides

nasty-shy [4]

Answer:

8 more widgets

Step-by-step explanation:

Monday:

t hours work AT w widgets per hour

So,

total number of widgets = wt

Tuesday:

2 fewer hours than monday, so

hours worked = t - 2

Per hour widget production is 4 more than Monday so:

per hour widget = w + 4

Total number of widgets = $(t-2)(w+4)=wt+4t-2w-8$

Monday he produced more, so amount more is:

$wt-[wt+4t-2w-8]\\wt-wt-4t+2w+8\\-4t+2w+8$

Given, w = 2t, we have:

$-4t+2w+8\\-4t+2(2t)+8\\-4t+4t+8\\=8$

Thus,

8 more widgets were produced
