Rita is a nurse. her regular rate is $32 per hour. she is paid double-time (two times the hourly rate) for holidays. during one week, she worked 36 regular hours plus 8 holiday hours. find her total earnings for the week.

32(36) + 8(64)
Rite earned $1664

$32x36 hours = $1,152 for 36 regular hours of work

Double-time is the hourly rate times 2, so $32x2=$64 per hour on double-time

$64x8=$512 for 8 hours on double-time

$1,152+$512=$1,664 is her total earnings for the week

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
