I would say the answer is 116
Answer:
A) correct
B) 1500mL × 0.01695 = $25.425
C) 1500mL × 0.0199 = $29.85
Step-by-step explanation:
Problem A looks correct
The least expensive way to buy 1,500mL of the cleaner is the one with the lowest price per mL:
1500mL × 0.01695 = $25.425
The most expensive way is the one with the highest price per mL:
1500mL × 0.0199 = $29.85
Answer:
3 vegetable trays, 2 sandwich trays
Step-by-step explanation:
I'm not quite sure what we're supposed to find, but if we were to find how many of each we can buy with $120 it would be 3 vegetable trays and 2 sandwich trays.
20 + 20 + 20 = $60
30 + 30 = $60
60 + 60 = $120
Answer:
a) 1/5 bucket = 1 gallon
b) 8.4 buckets = 1 barrel
c) 5376 fl oz per barrel
Step-by-step explanation:
a) From the given information, 1 bucket = 5 gallons. This means 1/5 of a bucket is 1 gallon.
b) From the given information, 8.4 buckets = 1 barrel. This seems to be in the form that the question is asking for. If the question was asking how many barrels were in a bucket the answer would be 1/8.4 barrels = 1 bucket.
c) From the previously determined conversion factors, we can take ounces to barrels by converting barrels down to gallons.
1/8.4 barrels = 1 bucket; 1/5 bucket = 1 gallon; 1 gallon = 128 fluid ounces
We need to set up a series of fractions that use these factors:
These fractions can be simplified to
Multiply the fractions: 5376 fl oz per barrel
(Note that the units cancel out in the fractions so that only fluid ounces per barrel are left.)
The answer is C. I solved for the first variable in one of the equations then substitute the result into the other equation.
