Answer: 12 minutes
Step-by-step explanation:
Two rates for hoses A and B. FP is the Fish Pond.
A = 20 min/FP or (1/20)FP/min
B = 30 min/FP or (1/30)FP/min
The time in minutes, X, to fill one FP:
1FP = X*((1/20)FP/min) + X*((1/30)FP/min)
1FP = X*(1/20+1/30)FP/min
1FP = X*(2.5/30)FP/min
X = 12 minutes
Answer: $105.84
Step-by-step explanation:
20/100 = x/87.37
*cross multiply*
20*87.37 = 100x
1747.4 = 100x
*divide*
1747.4/100 = x
17.474
*add*
87.37 + 17.474
105.844
*round*
