Mark is taking pledges for a bike-a-thon fundraiser. John pledged $3.75, plus $1.45 for each mile that Mark bikes. Kiara pledged $6.25, plus $0.55 for each mile that Mark bikes. Part A. Write expressions for the number of dollars John pledged and the number of dollars Kiara pledged. Use m for the number of miles that Mark bikes.

The expressions for

a) The number of dollars John pledged

= 3.75 + 1.45m

b) The number of dollars Kiara pledged = 6.25 + 0.55m

Step-by-step explanation:

Mark is taking pledges for a bike-a-thon fundraiser.

Part A.

Write expressions for the number of dollars John pledged and the number of dollars Kiara pledged.

Let us represent the number of miles that Mark bikes = m

John pledged $3.75, plus $1.45 for each mile that Mark bikes.

$3.75 + $1.45 × m

= 3.75 + 1.45m

Kiara pledged $6.25, plus $0.55 for each mile that Mark bikes.

$6.25 + $0.55 × m

= 6.25 + 0.55m

Therefore, the expressions for

a) The number of dollars John pledged

= 3.75 + 1.45m

b) The number of dollars Kiara pledged = 6.25 + 0.55m
