During a sale at h& m, you buy three sweatshirts and two pairs of pants for $85.50. later in the day, your friend buys three sweatshirts and four pairs of pants for $123. define your variables and write a system of equations to represent the situation if you wanted to find out how much each item costs individually.

so that, sweatshirts cost$16 and pants cost $18.75

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

.there can be infinite values of m and n that can satisfy the above equation. for each value of m of m or n. there maybe infinite sets of solution for the above
