COMMUNITY SERVICE Real World Example
In a canned food drive, Sam collected 12 more SHOPPING
cans than Louise. Together, they collected 128 Tami spent $175 at the grocery store. That is $25
cans. How many cans did Sam collect?
less than four times as much as Ted spent. How
much did Ted spend?
Let x = number of cans collected by Louise.
Then x + 12 = number of cans collected by Sam.
A. $8.33
B. $37.50
x + (x + 12) = 128 Write the equation.
C. $50
D. $600
(x + x) + 12 = 128 Associative Property.
2x + 12 = 128 Combine like terms.
2x + 12 – 12 = 128 – 12 Subtract 12 from each Answer
side.
2x = 116 Simplify.
x = 58 Mentally divide each side
by 2.
So, Louise collected 58 cans
Answer and Sam collected 58 + 12
or 70 cans.
