The function p(w)=238(1.6)^w represents the number of specialty items produced at the old factory w weeks after a change in mana

Alexxandr [17]

a.) w = 0

Old factory: $p(w)=238(1.6)^w$ Plug in 0

$p(0)=238(1.6)^0$

When a number has an exponent of 0, the number becomes 1

p(0) = 238(1)

p(0) = 238

New factory: w = 0, p(0) or y = 190 (0,190)

238 - 190 = 48

During Week 0, 48 more specialty items were produced at the old factory than at the new factory.
