Step-by-step explanation:
Step-by-step explanation:
Step:1
From given, the rate is
= 15 miles per gallon
= \frac{15}{1}115 = 15 miles.........................(1)
Step:2
Check for Option A,
= 30 miles per 3 gallons
= \frac{30}{3}330 = 10 miles.....................(2)
From the eqn (1) and (2),
Eqn (1) ≠ Eqn (2)
Step:3
Check for Option B and C are not match with given because, Miles provided first or top then the gallons provided the last or bottom.
Step:4
Check for Option D,
= 60 miles per 4 gallons
= \frac{60}{4}460 = 15 miles.........................(3)
From the eqn (1) and (3),
Eqn (1) ≠ Eqn (3)
Result:
The equivalent unit rate for 15 miles per gallon is 60 miles per 4 gallons (\frac{60 miles}{4 gallons}4gallons60miles ) .
The ratio of selling price to cost price is. 3.65 : 1.72
The cost price is 28.50 and you want to find the selling price so let x replace that spot
x : 28.50
cross multiply 3.65 × 28.50 and 1.72 × x
3.65 × 28.50 = 104.025
1.72 × x = 1.72x
104.025 = 1.72x
x is approximately $60.48
