a.r + 1.50 = 1.5r
b. r + (5 – r) = 5
c. 1.5r + 2.5(5 – r) = 10.50
d. 1.5r + 2.5(5 – r) = 5

Answer:
Step-by-step explanation:
Define 'r' as the quantity of raisins.
The overall mixture weighs 5 pounds.
This means the amount of peanuts is 5 minus r.
The cost for raisins is $1.50 per pound, while peanuts are priced at $2.50 per pound.
Setting up the equation: 1.50(r) + 2.50(5 - r) = 10.50.
Substituting values, we replace raisins with 'r' and peanuts with (5-r).
This forms our necessary equation.

Step-by-step breakdown:
Given,
Total cost of the bike including taxes = $349
Initial payment = $100
Remaining balance = Total cost of bike - Initial payment
Remaining balance = 349 - 100
Remaining balance = $249
She opts to pay in six equal installments, so we divide the total remaining by 6.
