Sarah sold a total of 178 t shirts and posters at a festival. She sold 46 more tshirts than poster. How many posters did she sel
ycow [4]

Sarah sold 66 posters

<em><u>Solution:</u></em>

Let "a" be the number of shirts sold

Let "b" be the number of posters sold

<em><u>Sarah sold a total of 178 t shirts and posters at a festival</u></em>

Therefore,

number of shirts sold + number of posters sold = 178

a + b = 178 ----------- eqn 1

<em><u>She sold 46 more tshirts than poster</u></em>

Number of shirts sold = 46 + number of posters sold

a = 46 + b --------- eqn 2

<em><u>Substitute eqn 2 in eqn 1</u></em>

46 + b + b = 178

2b = 178 - 46

2b = 132

b = 66

Thus she sold 66 posters
