Question 1074836
Let {{{ y }}} = amount saved
Let {{{ x }}} = number of weeks money is saved
-------------------------------------------
Equation for Kenji:
(1) {{{ y = 214x + 108 }}}
Equatiion for Issac:
(2) {{{ y = 209x + 113 }}}
------------------------
To find the intersection of
these two lines, set (2) equal
to (1)
{{{ 209x + 113 = 214x + 108 }}}
{{{ 5x = 5 }}}
{{{ x = 1 }}}
In 1 week, they will have saved the same amount
------------------------
check answer:
(1) {{{ y = 214x + 108 }}}
(1) {{{ y = 214*1 + 108 }}}
(1) {{{ y = 322 }}}
and
(2) {{{ y = 209x + 113 }}}
(2) {{{ y = 209*1 + 113 }}}
(2) {{{ y = 322 }}}
OK
