124.8 ( money found ) ÷ 2 (gbe & his friend) = 62.4
Answer:
7 1/20
Step-by-step explanation:
9 2/5 ÷ 1 1/3 = 9 6/15 ÷ 1 5/15
= 141/15 ÷ 20/15
= 141/15 * 15/20
= 141/20
= 7 1/20
If e^(rt) is 3, then taking logarithms tells you
... rt = ln(3)
So, the time to triple the amount is
... t = ln(3)/0.0275 ≈ 39.95 . . . . years

The working out that is shown in the picture appears to be correct.
Given Number of shirts bought by Jamal in Massachusetts =4.The question is asking us to find the money spent by Jamal after paying sales tax at the rate of 5% when cost of each shirt is $16.
Cost of 1 shirt= $16
Cost of 4 shirts = 4x16=$64.
Sales tax on the shirts = 5% =0.05(in decimal form)
Sales tax on 4 shirts costing $64= 0.05x64= $3.2
Cost of shirt including sales tax= 64+3.2=67.2
Jamal spend $67.2 on purchasing the shirts.
