Abike shop sells you a bicycle for $63 and a helmet for $21. the total cost is 150% of what the shop spent originally. how much did the shop spend originally

The shop spent $56 originally.

Step-by-step explanation:

Suppose, the shop spent dollars originally.

Given that, the total cost is 150% of what the shop spent originally. So, the total cost will be:   dollars.

The shop sells you a bicycle for $63 and a helmet for $21. So, the total cost

Thus, the equation will be.........

So, the shop spent $56 originally.

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)

the one that has a slope of 1/2 and is positive.

step-by-step explanation: 2 buckets 1 trip ; 4 buckets 2 trips and so on.
