1. mrs. nelson wants to buy a wireless speaker for her son. she has narrowed down her choice to two stores:
• kohl’s is selling the speaker for $60.00. mrs. nelson has a friends and family discount coupon for 25% off.
• target purchased the speaker for $38.00 and marked it up by 15% to sell to its customers.

a.) how much would mrs. nelson pay for the speaker at kohl’s? show your work.

b.) how much would mrs. nelson pay for this speaker at target? show your work.

c.) which store would mrs. nelson get the best deal and by how much? show your work.

x =-.20752

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752

in mathematics, a constraint is a condition of an optimization problem that the solution must satisfy. there are several types of constraints—primarily equality constraints, inequality constraints, and integer constraints. the set of candidate solutions that satisfy all constraints is called the feasible set.

hoped i'm right lol
